Data caching between nodes in a Mobile Ad hoc Network (MANET) has been an important consideration now a day. However most of the research works focus on ensuring security, routing, and research on maintaining cache consistency within MANETs. Here we focus on providing cache consistency in a mobile environment so as to increase the probability of data from caching nodes instead of from the server. Moreover, to ensure cooperative cache consistency we go in for Server Initiated Push (SIP) update mechanism in MA-NETSwhere server maintains a registration table for all registered clients and update those registered, by pushing the updated data, as and when the server gets refreshed. Here only registered clients that have registered are updated frequently, there by not compelling unregistered clients to receive the data update. This cache consistency mechanism for cooperative caching ensures reduced bandwidth utilization, less query latency, besides it also decrease the communication overhead and network traffic at the data server.
