A Technique for Construction of Overlay Networks for MANETs with Consideration of Physical Network Topologies

Recent years, the mobile ad hoc networks (MANETs) research community has been very active. Thus, it is of growing importance to build distributed network applications on top of MANETs. DHT is known as a popular technique to build efficient distributed applications in the Internet. However, in MANETs, DHT needs to consider network traffics, moving of nodes and energy efficiency more carefully than the Internet. We propose a technique for construction of overlay networks for MANETs in consideration for topologies of physical networks. Our technique realizes the pure P2P network that does not require special nodes like cluster heads or super peers. It gives a node ID to each node in a network using information from physically neighbor nodes so that the node has a node ID value close to that of neighbor nodes. Thus the neighbor nodes in the physical network will be also close in the logical network. When a node moves, a node ID will be reallocated to meet the above requirement. We evaluate the performance of the proposed technique by the simulations.
