Geographic routing has become one of the most suitable routing strategies in wireless mobile ad hoc network mainly due to its scalability. That is because there is no need to maintain explicit routes. The principle approach in geographic routing is greedy forwarding, which fails if the packet encounters a void node (i.e., a node with no neighbour closer to(More)
Geocasting is a variation of traditional multicasting in which the goal is to deliver a packet to all nodes within a geographical area often referred to as a geocast region. Several protocols have been designed for geocasting in mobile ad hoc networks (MANETs) which focus on how to route packets to the geocast region efficiently, while packet delivery(More)
Mobile Ad-hoc Networks (MANETs) are self-managing network which consists of distributed nodes that communicate with each other through wireless links with no fixed infrastructure and no centralized control. Due to self-configuring and dynamic nature of these networks routing protocol are susceptible to various types of attacks. The black hole attack is one(More)
