An ad hoc mobile network is a collection of mobile nodes that are arbitrarily located without any available fixed infrastructure. In such networks, change in interconnections between nodes depends on the movement of mobile nodes. Each mobile node acts as a router and moves in a discretionary manner. Due to dynamic topological changes and the lack of a fixed infrastructure, the problem of how to improve connectivity to guarantee delivery of information is one of the biggest challenges of ad hoc networks. One possible solution is to increase the transmission range of mobile nodes until the connectivity requirement is achieved. But due to physical restrictions, this solution is not always feasible.
