Localized routing with guaranteed delivery and a realistic physical layer in wireless sensor networks
Routing is the problem of sending a packet from a source node to a destination node in the network. Existing solutions for sensor networks assume a unit disk graph model, where messages between nodes are received correctly if and only if the distance between them is up to the transmission radius, which is equal for all nodes. Sensor networks require localized solutions, where nodes make decisions based on their own positions, the positions of their neighbouring nodes and the position of the destination. Existing localized routing algorithms include greedy routing and GFG (with guaranteed delivery) for the unit disk graph model and expected progress routing for a physical layer model. In a physical layer model, the packet reception probability depends on the distance between nodes. We propose to combine the expected progress routing with face routing to define a localized routing algorithm that guarantees delivery under realistic physical layer models. The proposed localized routing pr...
