Applying P2P in MANETs for resource sharing

A Mobile ad hoc network consists of wireless mobile nodes dynamically forming a temporary network without the use of existing network infrastructure or centralized administration. MANETs are formed with the key motivation that users can benefit from collaborations with each other. The applications based on these should be designed to operate in a decentralized manner. In recent years, Peer-to-Peer systems consisting of a dynamically changing set of nodes connected via the internet have gained popularity. P2P has emerged as a general paradigm for the construction of large-scale, distributed services. Many characteristics of P2P like (i) a flat and frequently changing topology, caused by node joining and leaving (ii) hop-by-hop connection establishment enables its applicability in MANETs as means of resource sharing. There are two types of P2P system among the two, the unstructured P2P best suites for MANET applications. We can use the muti-layered overlay structure to enable resource sharing. The hello beacons can be sent with other required fields to form the overlay structure. Each node whenever it receives a beacon packet should store the required details in the local cache and use that information during resource discovery. Since these information may change based on the nodes mobility the resource identification may need on demand request query to be broadcasted to the nodes in the network.
