Energy-Efficient Bootstrapping Protocol for Sensor Networks

Sensor networks are poised for increasingly wider uses in many military and civil applications. We present a bootstrapping protocol for a class of sensor networks in which the network has high-energy entities called gateways apart from the low-energy sensors. Most research activity in the field of sensor networks focuses on organizing the network and then proceeds to look for energy saving. However, we argue that bootstrapping done inefficiently can be a major source of energy wastage. We present an energy-aware mechanism for initializing the network. Our proposed approach focuses on avoiding collisions in the bootstrapping phase and stresses on keeping receiver/transmitter units off whenever possible to preserve energy. In addition, our mechanism synchronizes the sensor nodes to the gateway’s time base so that TDMA based communication can be used. We study the performance of our mechanism using simulation and compare it to the performance of a basic approach in which sensor nodes h...
