Most previously proposed position based routing algorithms for wireless ad hoc networks were based on forwarding the actual message along multiple paths toward an area where destination is hopefully located. The significant communication overhead can be avoided if the routing strategy is changed. We propose that the source node issues several search 'tickets' (each ticket is a 'short' message c...

Privacy is needed in ad hoc networks. In order to provide anonymous routing protocol in MANETs the location of source and destination can be concealed by using “notify and go” mechanism and broadcasting. In this paper, we address some of the issues arising in MANETs by using an anonymous routing protocol. Location Based Anonymous Routing Protocol partitions the network into zones for anonymity ...

Wireless sensor networks are widely used in our daily life. It consists of various sensors which collect different information containing the identity, status, and location of an object or any other business, social or privately relevant information. But we pay attention to some issues related to sensor’s location privacy. In this paper, we focus on protecting the sensor’s location by introduci...

Routing for ad-hoc wireless network is challenging, many routing strategies have been proposed in literature. With the availability of affordable Global Position System equipped devices, location-aware routing provides a promising foundation for developing an efficient and practical solution for routing in ad-hoc wireless network. Current geographic forwarding strategies and geographic routing ...

Ad hoc networks are gaining increasing popularity in recent years because of their ease of deployment. No wired base station or infrastructure is supported, and each host communicates one another via packet radios. In ad hoc networks, routing protocols are challenged with establishing and maintaining multihop routes in the face of mobility, bandwidth limitation and power constraints. In this pa...

The thesis first analyses the importance sensor placement has in a large scale WSN application using geographic routing. A simulation-based topological study is made for a forest fire prevention application using both deterministically and randomly placed nodes. Sensor deployment can be projectile, from the network edge, made through manual scattering or by air release. Results reveal the impac...
