Virtual base stations for wireless mobile ad hoc communications: an infrastructure for the infrastructure‐less

Abstract

SUMMARYIn this paper, we propose a new protocol for wireless mobile ad hoc networks, which establishes a dynamic wireless mobile infrastructure. The proposed protocol, namely, the virtual base stations (VBS) protocol, mimics and maintains the operation of the conventional "xed infrastructure in cellular networks. In the VBS protocol, a mobile node is elected from a set of nominees to act as a temporary base station within its zone. We provide proofs for the correctness of the VBS protocol, and show lower and upper bounds for its global convergence time. Likewise, we study the characteristics and performance of VBS by means of simulation. It is shown that VBS scales well to large networks of mobile stations, and that it outperforms other infrastructure-formation protocols in terms of stability. The VBS protocol would facilitate the development of a comprehensive and promising framework for quality of service (QoS) management in wireless mobile ad hoc networks once the proper integration of the MAC protocol with the routing and call admission control mechanisms is established. The VBS architecture lays the groundwork for assigning bandwidth, and/or implementing priorities, and hence for QoS-based routing by conveying the quality of a path prior to call setup.

Wireless Ad Hoc and Sensor Networks

“…GPC [46] Single Clustered N/A yes High Density 26. VBS [47] N/A Clustered N/A no Voice 27. DPC/ALP [48] Single Multiple/Flat sender yes Heterogenous 28.…”

“…The Virtual Base Station (VBS) [47] protocol focuses on a dynamic random selection of a virtual base station for clusters in mobile networks. In VBS, each node announces its IP address periodically by sending "hello" messages to its neighbors.…”

Energy-aware routing in MANETs

“…A wireless station is chosen by one or more stations to act as their PA-VBS based on a couple of energy thresholds. Unlike other clustering schemes [16], [7], [17], and [3], it allows the mobile nodes to use their valuable battery power fairly; it does not drain all the battery capacity of the clusterheads since it introduces the concept of service denial, and, hence, it attains fair clustering. PA-VBS is also shown, in our simulation experiments, to react positively to different routing loads.…”

Energy Aware Database Updating Protocols for Autoconfigurable Sensor Networks

“…In paper [3], H. Hassanein and A. Safwat propose a Virtual Base Station protocol which mimics and maintains the operation of conventional fixed infrastructure in cellular networks. In the Virtual Base Station protocol, a mobile node is elected from a set of nominees to act as a temporary Base Station within its zone.…”

“…Mobile terminals elected as VBS are used to track other mobile stations in the ad hoc network. Neither [3] nor [4] take energy into consideration.…”
