“…Research into the creation of infostations and other mobility caching systems, all recognize the transportation aspect of mobile communication [30]. In a very specific scenario, researchers describe a system in which individuals who walk by associated hotspots might receive data as they walk, both from the hotspot and from information intentionally cached on the PDAs of other pedestrians [31]. The authors point out that most ad hoc network simulations assume no knowledge of the node's future movement path and that this assumption is not valid in many situations.…”

Abstract-Wireless networks combined with location technology create new problems and call for new decision aids. As a precursor to the development of these decision aids, a concept of communication distance is developed and applied to six situations. This concept allows travel time and bandwidth to be combined in a single measure so that many problems can be mapped onto a weighted graph and solved through shortest path algorithms. The paper looks at the problem of intercepting an out-of-communication team member and describes ways of using planning to reduce communication distance in anticipation of a break in connection. The concept is also applied to ad hoc radio networks. A way of performing route planning using a bandwidth map is developed and analyzed. The general implications of the work to transportation planning are discussed.

“…By abstracting functionality into distinct agents, our framework is highly modular and loosely coupled. eNcentive was built as an application on top of an in-house agent framework called Numi [14,11]. Numi was built to address data management needs of mobile devices moving through a geographical region offering hybrid wireless support (combination of infrastructure based and ad hoc wireless technologies).…”

In recent years, the growth of Mobile Computing, Electronic Commerce and Mobile Electronic Commerce has created a new concept of Mobile Electronic Marketing. New marketing models are being developed and used to target mobile users. Mobile environments introduces new challenges that need to be overcome by these marketing models in order to be successful and effective. This paper proposes a framework, called eNcentive, which addresses many of the issues that are characteristic of mobile environments. eNcentive facilitates peer-to-peer electronic marketing in mobile ad hoc environments. Our framework employs a intelligent marketing scheme, by providing users the capability to collect information like sales promotions and discounts. Users can propagate this marketing information to other users in the network. Participating users benefit from such circulation since businesses that originally created the promotions reward the active distributors with additional promotions and other compensations.

“…Other frameworks or systems, include [4], [1], [8], NUMI [3], and M 2 -WLAN [2], use peer-to-peer communication to assist the infrastructure-based system for data exchange or distribution. [8] did an initial study on using non-cooperative mechanism, e.g., peer-to-peer communication, to improve the efficiency of content distribution for the infostation system.…”

“…Two encountered mobile nodes check the file content lists of each other, identify some files they need, and exchange those files. In NUMI [3], the APs collaborate among themselves and can predict the mobile node's location in the near future. Using this information, the AP is able to select another mobile node, which is likely to move around the vicinity of the destination mobile node, to piggyback the requested data for the destination mobile node.…”

In traditional all . IntroductionWireless local area networks have come into great use in recent years. Although a variety of wireless network technologies have been in the market, wireless LANs based on the IEEE 802.11 standard are the most popular. There are two operation modes, i.e., the infrastructure mode and the ad hoc mode, specified in IEEE 802.11 standard. In the ad * This work was partially supported by the National Science Council and the Ministry of Education of ROC under the contract No. NSC92-2622-E-002-002 and 89E-FA06-2-4-8.hoc mode, all mobile nodes are free to directly communicate with each other in a peer-to-peer manner. Another option of the operation mode in WLAN is the infrastructure mode, where each mobile node associates itself with an access point (AP) within its direct transmission range. The AP is connected to a wired network and provides a conduit to the external network for the mobile nodes. Communications can only take place between the wireless node and the AP but not directly between the wireless nodes.In this paper, we consider the problem of distributing popular data at the server to users in a wireless LAN environment. The data dissemination problems correspond to a set of important applications. These applications include distribution of course slides in a class, dissemination of useful information in the info-station, online documents distribution in a conference, and many more. In a traditional infrastructure-based WLAN, all communications will go through the APs, but an AP can only provide a certain amount of bandwidth (e.g., 802.11b is 11 Mbps) for all users within its transmission coverage. In such wireless network environment, there are two major inefficiencies: (a) load imbalance problem among the APs: when the distribution of the location of the mobile nodes is non-uniform, this might lead to a situation where a lot of nodes access a single AP but other APs are idle, and (b) poor resource utilization: most of the nodes contend for the wireless channel of the AP while there are still some unused but available wireless channels, which can be used to set up ad hoc groups. When the number of users increases within an AP's cell, the contention for the wireless channel will lead to more collisions, degradation in system throughput, and longer data delivery time for the mobile nodes. To increase the system throughput and reduce the user's response time, a simple solution is to allocate more bandwidth for users by installing more APs, which use different wireless channels, but this approach is expensive and not flexible to deal with the "temporary" fluctuation of the network load.In a wireless network environment, an important observation for the data dissemination applications is that most local users are interested in nearly the same set of objects.
