A Time Index Based Approach for Cache Sharing in Mobile Adhoc Networks
Initially wireless networks were fully infrastructure based and hence imposed the necessity to install base station. Base station leads to single point of failure and causes scalability problems. With the advent of mobile adhoc networks, these problems are mitigated, by allowing certain mobile nodes to form a dynamic and temporary communication network without any preexisting infrastructure. Caching is an important technique to enhance the performance in any network. Particularly, in MANETs, it is important to cache frequently accessed data not only to reduce average latency and wireless bandwidth but also to avoid heavy traffic near the data centre.
