are mobile resulting in dynamic topology with high rate of link breakage and network partitions leading to interruptions in the ongoing communication. In contrast to wired network, MANET has increased possibility of packet loss and congestion resulting in energy consumption. Routing techniques help in path establishment for transmission. The existing routing protocols suffer from overhead causing energy loss which may be further aggravated by link failures. This survey discuss about the conventional routing protocols that are prime candidates for the study of overhead and link failure problems. And also reviewed the various approaches proposed in the literature to make conventional routing protocols energy efficient. Keywords-Ad hoc network; energy consumption; routing protocols; overhead; link I.

The goal of this report is to document the theoretical and practical issues of mobile ad-hoc networks (MANETs) and distributed database systems build upon Peer-to-Peer middleware. Focus in this report is given to the modelling of network and query layers. Furthermore, we discuss the design and testing of essential parts of such a system. Thus we want to show the potential of using a Peer-to-Peer middleware to implement fine grained querying. The specific application case used, is that of a wireless ad-hoc network, where nodes represent trucks containing a small subset of a collective inventory. The
