Tightly Cooperative Caching Approach in Mobile Ad Hoc Network

Mobile Ad hoc Network (MANETs) relies on cooperation of all participating nodes. All mobile nodes may easily vulnerable to selfish/malicious nodes which can lower down data communication and degrade the network performance due to refusal of relaying packet in order to save their own resources such as power, time, etc. These non-cooperative behaviors become challenging in cooperative caching system which mainly depends on cooperative nodes. To solve this problem, we propose tightly cooperative caching approach (TCCA) to encourage all nodes to aggressively cooperate by using enhanced credit-based distribution algorithm based on the resource status of the mobile nodes and the demand volume of the request to have load balancing among the acceptor nodes and requester nodes. According to the experimental results, our approach gets the superior results than other approaches under different parameter setting of nodes and network structure.
