Coordinated Robust Routing by Dual Cluster Heads in Layered Wireless Sensor Networks
In this paper, we propose the coordinated robust routing (CRR) scheme to address the fault tolerance requirements in the layered wireless sensor networks. In the proposed scheme, ...

A decentralised coordination algorithm for minimising conflict and maximising coverage in sensor networks
In large wireless sensor networks, the problem of assigning radio frequencies to sensing agents such that no two connected sensors are assigned the same value (and will thus inter...
