A Cluster Based Collaborative Cache Approach for MANETs

The main contribution of this work is to propose a distributed and collaborative cache solution in which the decisions to cache objects are performed in a collaborative way. In our solution, objects are classified in private and shared objects. Private objects are managed as in an individual cache system whereas the management of shared objects are performed collectively and are stored in a shared area. The simulation results have shown that our solution can expressively reduce the server load by increasing cache diversity and the probability of cache hits. Also, our solution provides significant savings in terms of battery power and congestion on the routes towards the sink node.
