An Adaptive Mesh - based Protocol for Geocast
نویسنده
چکیده
This article concerns a variation on multicasting, called geocasting, for an ad hoc network. The goal of a geocast routing protocol is to deliver packets to a group of nodes that are within a specified geographical area, i.e., the geocast region. This paper presents a Geocast Adaptive Mesh Environment for Routing (GAMER) which provides geocast communication in an ad hoc network. GAMER adapts to the current network environment by dynamically changing the density of the mesh. Thus, when nodes are highly mobile, a dense mesh is created; when nodes are moving slowly, a sparse mesh is created. We compare the performance of GAMER with non-adaptive mesh-based geocast routing protocols in an ns-2 simulated ad hoc network. We also compare two versions of GAMER; one version is more active than the other in adapting to the current network environment. We conclude that both versions of GAMER improve the transmission accuracy significantly, without increasing the load on the network significantly, when compared to non-adaptive mesh-based geocast routing approaches.

متن کاملA Review of Geocasting Protocols for a Mobile Ad Hoc Network∗ †
A mobile ad hoc network (MANET) is a network consisting of a set of mobile hosts capable of communicating with each other without the assistance of base stations. In this paper we review five existing protocols for geocasting in a MANET environment. The goal of a geocasting protocol is to deliver data packets to a group of nodes that are with a specified geographical area, i.e., the geocast reg...

Cooperative Adaptive Cruise Control (CACC) is a type of cruise control in which the speed of a vehicle is controlled based on wireless communication between vehicles. In this paper we tackle the communication needed in case of fully automatic CACC merging at a junction. The first contribution of our paper is to show that to target the vehicles involved we need a special kind of geocast that tak...
