In wireless sensor networks (WSNs), long lifetime requirement of different applications and limited energy storage capability of sensor nodes has led us to find out new horizons for reducing power consumption upon nodes. To increase sensor node's lifetime, circuit and protocols have to be energy efficient so that they can make a priori reactions by estimating and predicting energy consumption. The goal of this study is to present and discuss several strategies such as power-aware protocols, cross-layer optimization, and harvesting technologies used to alleviate power consumption constraint in WSNs.

“…To fulfill this goal, several papers have focused on techniques to relay data efficiently in order to reduce energy consumption [20], [3] or to guarantee that messages are delivered to their recipients [2], [13]. We focus on collision avoidance: as shown in [8], most energy is consumed by communications between sensors. A collision causes the sensor to transmit the message again, which wastes energy.…”

Clustering and communications scheduling in WSNs using mixed integer linear programming

We consider the problem of scheduling communications in Wireless Sensor Networks to ensure battery preservation through the use of sensors' sleeping mode. We propose a communication protocol in 1-hop WSNs and extend it to multi-hop WSNs thanks to a 1-hop clustering algorithm. Once the clustering is obtained, we propose to schedule communications in a virtual communication ring so as to avoid collisions. Since clusters are complete, only one sensor can speak or listen in a cluster at a time, and all sensors need to speak in each of their clusters at least once to achieve the communication protocol. We model this situation as a mathematical program.François Avril is with the CaRO

In wireless sensor networks (WSN), one of the most important challenges is power saving, then various contributions are suggested since a decade. In this paper, we propose a distributed and adaptive gossiping technique able to guarantee communications over all sensors and to save a high amount of energy. The aim is to allow to the network to achieve a self-organizing procedure in order to provide an efficient structuring approach for communications over all sensors. The medium access will be TDMA (Time Division Medium Access) like. Indeed, each sensor will have a particular slot for listening and another one for sending. The slot assignment is achieved in a distributed manner and is continuously reconfigurable. That means when a sensor leaves the network, its assigned slot will be recovered and when a new one wants to join the network, the last available slot will be assigned to it.
