Game theory MANET routing for jamming environment

Bohacek, Stephan K.A Mobile Ad Hoc Network (MANET) is a set of self-organizing wireless mobile nodes, which communicate with each other without any existing network infrastructure or centralized network management. Wireless communication over MANET follows a multi-hop manner, in which each node can be a transceiver or a router. MANET has spurred considerable research interests and applications in the felids of vehicle network, sensor network and tactical communication network. Tactical communication network works in a highly dynamic environment with the kinds of interferences and jammings, which can cause low packet delivery rates, long delays or even interruptions. Moreover, the effects may spread across multiple network protocol stacks, typically physical (PHY) layer and media access control (MAC) layer. Because of the interruptions and jammings, MANET routing algorithms must be robust enough to give reliable network services. Furthermore, since the end-to-end communications of MANET are achieved via multi-hop relays, the routing protocol is an essential factor that affects the overall performance of MANET. The Optimized Link State Routing (OLSR) is a routing protocol for MANET, which is built on the classical link state algorithm with multi-point relays (MPRs). OLSR has been shown to be suitable for large-scale dense wireless networks. In this thesis, we developed and implemented a game theory routing protocol (GTR) based on conventional OLSR for jamming environment. With game theory, GTR makes probabilistic decision according to the jamming conditions. GTR have been put in place over OLSR in Qualnet network simulation tool. Impacts of jamming on GTR and OLSR are studied. The results show that GTR has better overall performance, specifically lower end-to-end delay and higher packet delivery rate, over OLSR.University of Delaware, Department of Electrical and Computer EngineeringM.S
