“…As in [16], once the requested data item reaches the requesting cache node, for instance X, it caches the data item along with the next update time and time of departure. Every node maintains a cache node information table having details of all the other cache nodes in order to provide for cooperative caching similar to the index vector in [17]. This table has the parameters of the cache node ID and the list of items cached by the respective cache nodes.…”

Abstract:Maintaining data consistency between data cached by a mobile client and data residing in the data server is a major issue in a wireless mobile environment. In this paper, we propose a push-pull cache consistency (2P2C) mechanism, with the intention of increasing the rate of serving requestors with recent up-to-date information or data from the cache of the intermediate nodes that are exact replicas of the data present in the origin server. This is a hybrid scheme that does not rely entirely either on the server or on the mobile client for maintaining consistency. Here we employ a registration process. Based on the registration process, the proposed 2P2C mechanism follows both a serverbased consistency scheme and a client-based consistency scheme. Besides this, both the server and the cache nodes can legitimately accept client registrations. Hence, this 2P2C method highly decreases unnecessary communication overhead incurred in the network and thereby considerably reduces access latency.

“…Lim et al (2006) suggested a caching algorithm to minimize the delay while acquiring data. To the best of our knowledge, only few of previous works (Chand, Joshi, & Misra, 2006;Chiu & Young, 2009;Chand, Joshi, & Misra, 2007) have exploited clustering as caching mechanism in MANETs. Cooperative caching has been studied in web environment (Malpani, Lorch, & Berger, 1996), but efficient cache management is still a hot research area in MANETs.…”

“…In a multihop MANET environment, discovering an available copy of a needed data item is the core of a caching scheme. Existing protocols (Chiu & Young, 2009;Lim, Lee, Cao, & Das, 2004) rely on flooding mechanism to locate a data item. Although flooding may potentially reduce the response time for a data request, it leads to excessive communication overhead.…”

“…Although flooding may potentially reduce the response time for a data request, it leads to excessive communication overhead. The problem could be dealt by imposing a threshold on route existence probability of request packet (Chiu & Young, 2009). A scheme for caching, locating and streaming multimedia objects in mobile networks was proposed in (Lau, Kumar, & Venkatesh, 2002).…”

“…To date there are some works in literature on cooperative caching in ad hoc networks, such as consistency (Yin & Cao, 2004;Chiu & Young, 2009), and placement (Tang, Gupta, & Das, 2008). In this paper, we investigate the data retrieval challenge of mobile ad hoc networks and propose a novel scheme, called global cluster cooperation (GCC) for caching.…”

Mobile ad hoc network (MANET) presents a constrained communication environment due to fundamental limitations of client’s resources, insufficient wireless bandwidth and users’ frequent mobility. MANETs have many distinct characteristics which distinguish them from other wireless networks. Due to frequent network disconnection, data availability is lower than traditional wired networks. Cooperative caching helps MANETs in alleviating the situation of non availability of data. In this paper, the authors present a scheme called global cluster cooperation (GCC) for caching in mobile ad hoc networks. In this scheme, network topology is partitioned into non-overlapping clusters based on the physical network proximity. This approach fully exploits the pull mechanism to facilitate cache sharing in a MANET. Simulation experiments show that GCC mechanism achieves significant improvements in cache hit ratio and average query latency in comparison with other caching strategies.
