A Distance-Based Energy Aware Routing Algorithm for Wireless Sensor Networks

Abstract

Energy efficiency and balancing is one of the primary challenges for wireless sensor networks (WSNs) since the tiny sensor nodes cannot be easily recharged once they are deployed. Up to now, many energy efficient routing algorithms or protocols have been proposed with techniques like clustering, data aggregation and location tracking etc. However, many of them aim to minimize parameters like total energy consumption, latency etc., which cause hotspot nodes and partitioned network due to the overuse of certain nodes. In this paper, a Distance-based Energy Aware Routing (DEAR) algorithm is proposed to ensure energy efficiency and energy balancing based on theoretical analysis of different energy and traffic models. During the routing process, we consider individual distance as the primary parameter in order to adjust and equalize the energy consumption among involved sensors. The residual energy is also considered as a secondary factor. In this way, all the intermediate nodes will consume their energy at similar rate, which maximizes network lifetime. Simulation results show that the DEAR algorithm can reduce and balance the energy consumption for all sensor nodes so network lifetime is greatly prolonged compared to other routing algorithms.

Wireless-powered cooperative energy aware anycast routing in wireless sensor networks

“…The proposed path deals with variable topology that was, in fact in the light of the path quality with the use of path differences and link disconnectivity enhancement. Wang et al 26 suggested distance-based energy aware routing (DEAR) protocol which not only assured energy efficiency but also ensured efficient load balancing. Diverse traffic and energy models have been utilized as premise to this protocol.…”

A Mobile Recommendation Algorithm Based on Statistical Analysis of User Data

“…The whole process is completed by two steps: the tool chooses the appropriate subset from the data set as the training set to gain training model firstly, and then uses the model to run the testing set to get the recommendation for the target user. This algorithm is simple to implement and it can avoid the disadvantages of data sparseness and cold boot, but its recommendation for the target user may be useless [15,16].…”
