Internet-based mobile ad hoc network (IMANET IMANET) is an emerging technique that combines a wired network (e.g. Internet) and a mobile ad hoc network (MANET MANET) for developing a ubiquitous communication infrastructure. To fulfill usersÕ demand to access various kinds of information, however, an IMANET IMANET has several limitations such as limited accessibility to the wired Internet, insufficient wireless bandwidth, and longer message latency. In this paper, we address the issues involved in information search and access in IMANETSIMANETS. An aggregate caching mechanism and a broadcast-based Simple Search (SS) algorithm are proposed for improving the information accessibility and reducing average communication latency in IMANETS IMANETS. As a part of the aggregate cache, a cache admission control policy and a cache replacement policy, called Time and Distance Sensitive (TDS) replacement, are developed to reduce the cache miss ratio and improve the information accessibility. We evaluate the impact of caching, cache management, and the number of access points that are connected to the Internet, through extensive simulation. The simulation results indicate that the proposed aggregate caching mechanism can significantly improve an IMANET IMANET performance in terms of throughput and average number of hops to access data items.

“…The requesting node (RN) will then issue a request for the data (unicast) to the first acknowledging node it hears from. However, the scheme is inefficient in terms of bandwidth usage because of the broadcasts, which, if frequent, will largely decrease the throughput of the system due to flooding the network [9].…”

Abstract-Cache look up is an integral part of cooperative caching in ad hoc networks. In this paper, we discuss a cooperative caching architecture with a distributed cache look up protocol which relies on a virtual backbone for locating and accessing data within a cooperate cache. Our proposal consists of two phases: (i) formation of a virtual backbone and (ii) the cache look up phase. The nodes in a Connected Dominating Set (CDS) form the virtual backbone. The cache look up protocol makes use of the nodes in the virtual backbone for effective data dissemination and discovery. The idea in this scheme is to reduce the number of nodes involved in cache look up process, by constructing a CDS that contains a small number of nodes, still having full coverage of the network. We evaluated the effect of various parameter settings on the performance metrics such as message overhead, cache hit ratio and average query delay. Compared to the previous schemes the proposed scheme not only reduces message overhead, but also improves the cache hit ratio and reduces the average delay.
