An ad hoc network is a temporary that consists of wireless mobile hosts. Due to the absence centralized or structured infrastructure, host may need assistance in forwarding packet desired location. This applicable cases whereby limited range transmissions visible Dynamic Source Routing (DSR) simple but effective protocol intended specifically for those networks lack predetermined infrastructure...

In the ad-hoc radio network model, nodes communicate with their neighbors via signals, without knowing topology of underlying digraph. We study information gathering problem, where each node has a piece called rumor , and objective is to transmit all rumors designated target node. For model any collision detection we provide an O ˜ ( n 1.5 ) deterministic protocol, significantly improving trivi...

Ad hoc networks enable network creation on the fly without support of any predefined infrastructure. The spontaneous erection of networks in anytime and anywhere fashion enables development of various novel applications based on ad hoc networks. However, ad hoc networks present several new challenges. Different research proposals have came forward to resolve these challenges. This chapter provi...
