"In this paper, the authors propose Distributed Cache Invalidation Mechanism (DCIM), a client-based cache consistency scheme that is implemented on top of a previously proposed architecture for caching data items in Mobile Ad-hoc NETworks (MANETs), namely COACS, where special nodes cache the queries and the addresses of the nodes that store the responses to these queries. The authors have also previously proposed a server-based consistency scheme, named SSUM, whereas in this paper, they introduce DCIM that is totally client-based. In this paper, DCIM is analyzed to assess the delay and bandwidth gains (or costs) when compared to polling every time and push-based schemes."
