Abstract:
Wireless sensor networks (WSNs) are composed of several sensors nodes with limited resources. Nodes can collect data in their deployed area and forward them to the sink using multi-hop communication.WSNs have limited energy and are generally deployed in harsh areas. So, it is not easy for humans to access and replace batteries. Thus, the lifetime of the network must be extended to allow data collection for a long time. To optimize energy consumption in low-power and lossy networks, the Routing Protocol for Low-Power and Lossy Networks (RPL) has been proposed. However, the energy consumption in RPL protocol is not fairly distributed. Some nodes are more solicited to forward data toward the sink node. As a result, the most solicited nodes deplete more quickly their energy, that lead to the network partitioning, data packets lost and more re-transmissions. In the literature, most of the proposed optimization techniques are not able to balance both routing load and power consumption. To address this challenge, in this paper, we present a routing technique based on children weights to fairly distribute children nodes among candidate parent nodes. Doing so helps all forwarding nodes in the network to have nearly the same traffic load. That permits to balance routing load and power consumption in the network. Analytical results show that our proposal is better compared to other improved RPL protocols using the Expected Transmission Count (ETX) and number of children metrics.
