Geographic Routing Around Obstacles in Wireless Sensor Networks
Geographic routing is becoming the protocol of choice for many sensor network applications. The current state of the art is unsatisfactory: some algorithms are very efficient, however they require a preliminary planarization of the communication graph. Planarization induces overhead and is not realistic in many scenarios. On the other hand, georouting algorithms which do not rely on planarizati...
متن کاملSecuring Geographic Routing in Wireless Sensor Networks
We consider the security of geographic routing (GR) that is widely used in ad hoc and wireless sensor networks due to its scalability. In GR, a node greedily forwards a packet to the neighbor that is closest to the destination. Thus, GR only requires a node to maintain the location information of its one hop neighbors. However, very little work has been done to secure GR. In a potential attack,...
متن کاملALBA-R: Load-Balancing Geographic Routing Around Connectivity Holes in Wireless Sensor Networks SUPPLEMENTAL MATERIAL
This paper presents ALBA-R, a protocol for convergecasting in wireless sensor networks. ALBA-R features the cross-layer integration of geographic routing with contention-based MAC for relay selection and load balancing (ALBA) as well as a mechanism to detect and route around connectivity holes (Rainbow). ALBA and Rainbow (ALBA-R) together solve the problem of routing around a dead end without o...
متن کاملSimple and Efficient Geographic Routing Around Obstacles for Wireless Sensor Networks
Geographic routing is becoming the protocol of choice for many sensor network applications. The current state of the art is unsatisfactory: some algorithms are very efficient, however they require a preliminary planarization of the communication graph. Planarization induces overhead and is thus not realistic for some scenarios such as the case of highly dynamic network topologies. On the other ...
متن کاملTowards Resilient Geographic Routing in Wireless Sensor Networks
In this paper, we consider the security of geographic forwarding (GF). In GF, neighbors exchange their location information. Based on the information, a node forwards packets to the neighbor that is closest to the destination. Although GF is widely used in ad hoc and wireless sensor networks, its security aspect has rarely been studied. There are a number of attacks that are possible on GF. In ...
