Geographic routing protocols show good properties for Wireless Sensor Networks (WSN). They are stateless, local and scalable. However they require that each node of the network is aware of its own position. While it may be possible to equip each node with GPS receiver, even if it is costly, there are some issues and receiving a usable GPS signal may be difficult in some situations. For these re...

Underwater wireless sensor networks (UWSN), similar to the terrestrial sensor networks, have different challenges such as limited bandwidth, low battery power, defective underwater channels, and high variable propagation delay. A crucial problem in UWSN is finding an efficient route between a source and a destination. Consequently, great efforts have been made for designing efficient protocols ...

A MANET is a self configuring infrastructure less networks. It is usually connected by wireless. Each device in a MANET is independently to move in any direction. To maintain neighbor position the geographic location coordinates of the node is a famous method used by most geographic routing protocol for the purpose of periodic broadcasting of beacon packets. If the location information is not a...

In this work we propose an UML modeling of the “Greedy Perimeter Stateless Routing” (GPSR) protocol that integrate this geographic routing protocol, into "JavaNetwork Simulator" to simulate and study this protocol in a first time and offer some improvement in these features. Java Network Simulator (JNS) is a project of "translation" of Network Simulator (NS) in Java initiated by "the UCL Depart...

In this paper, we introduce a new location-based routing protocol INGEO (INdoor GEOgraphic Routing Protocol) for ad hoc networks based on an indoor location system. We aim at extracting an optimum topology from the dynamic and irregular topology of a mobile ad hoc network to reach more quickly the destination applying an indoor geographic routing. Our scheme operates in a loopfree manner and at...
