Abstract:This
paper proposes to study the impact of malicious nodes on Mobile Ad hoc Networks
(MANETs). Due to their flexibility and independence from network infrastructure
like base stations, it is being widely researched. Routing in MANETs is more
challenging when compared to conventional networks due to various
characteristics like dynamic network topology, limited bandwidth and limited
battery power. Early research focused on developing efficient routing
mechanisms in dynamic and resource-constrained networks in MANETs. Most of the
routing protocols were suggested mainly based on the assumption of trust and
cooperative nature amongst the nodes. Thus, the MANET is vulnerable to
malicious node attacks. Geographic routing research, a recent approach compared
to topological routing received attention due to improved routing capability
resulting from accurate geographic information. This study investigates the
impact of malicious nodes on geographic routing; through simulations conducted
to evaluate network performance degradation caused by malicious node activity.
Simulation studies demonstrate that the networks with 15% malicious nodes show
significant performance degradation.
