Cluster-based routing protocol for mobile sensor networks
Liliana M. Arboleda C., Nidal Nasser · 2006
Hierarchical routing and clustering mechanisms in Wireless Sensor Networks (WSN) help to reduce the energy consumption and the overhead created when all the sensor nodes in the network are sending information to the central data collection point or base station. Most of the routing and clustering protocols currently used or proposed for WSN assume that the nodes are stationary. However, in applications like habitat monitoring or search and rescue, that assumption makes those clustering mechanisms invalid, since the static nature of sensors is not real. In this thesis, we present a Cluster-based ROuting protocol for MObile Sensor networks (CROMOS). The protocol considers the following design aspects: mobility of sensors, zones and routes maintenance, information update and communication between sensor nodes. A simulation model has been designed and developed to evaluate the performance of the proposed protocol. Simulation results and comparisons with different scenarios show the effectiveness and strengths of the CROMOS protocol. CROMOS shows a low routing and mobility overhead, while achieving a good performance in WSN using small zone sizes and sensors with low speed.
