Stimulating Node Cooperation in Mobile Ad Hoc Networks
Source: Iowa State University
Mobile Ad hoc NETworks (MANETs) rely on the cooperation of nodes for packet routing and forwarding. However, much of the existing works in MANETs assume that mobile nodes (possibly owned by selfish users) will follow prescribed protocols without deviation. However, a user may misbehave due to several advantages resulting from noncooperation, the most obvious being power saving. As such, the network availability is severely endangered. Hence, enforcing the cooperation among nodes becomes a very important issue. Several different approaches have been developed to detect non-cooperative nodes or deal with the non-cooperative behavior of mobile nodes in MANETs. These protocols are first surveyed in details in this paper.
