One area, which has already been identified as a focal point of research in MANET is routing with a number of routing protocols proposed in the last couple of years. However, a comparison between them is lacking to help deciding which routing protocol is best suited in specific network scenarios. The paper is presented the performance comparison of the protocols with identical loads and environmental conditions and summarized their relative performance in a tabular form with respect to some basic performance metrics. Moreover, this report focused on a clear view of range query applied in mobile ad hoc networks, different strategies to realize this range query and analysis of the results obtained from the implementation of the best suited strategy into ns2. The strategies to realize range queries are based on the criteria to collect location and other information of different nodes situated in an expected region in an ad hoc network. Several forwarding algorithms have been studied and measured for the accumulation of the suitable ones to realize range queries. Based on the theoretical concept of the different protocols and the strategy of the range query a proposed idea was given that can be used for efficient communication among the nodes.
