Abstract

In multi-hop wireless communication, a sensor node must consume its energy efficiently for relaying data packets. However, most of the IoT-devices are equipped with limited battery power and computing resources for wireless communication thus energy optimization becomes one of the major concerns in wireless sensors routing design. The wireless technologies usually use unlicensed frequency bands of 2.4 GHz to transmit the data. Due to the broadcasting medium, the wireless transmission interferes with the reception of surrounding radios. As a result, data transmission failure increases and thus low communication quality. Therefore, one of the best solutions of this problem is to select the hop distance node that has a few neighbour nodes to disseminate a packet until it reaches the ultimate receiver. The new routing selects the node that has few neighbouring nodes and thus less interference. In another word, the scheme finds a better load balancing and thus minimizes the probability of overload on a sensor node. It also introduces a new clustering algorithm around a single base station that could shorten the transmission distances. This approach periodically selects the cluster heads (CHs) according to its location from the final destination. Extensive simulation studies reveal that the proposed algorithm finds the best routing technique and clustering formation to forward the traffic and thereby minimizes the interference ratio. In addition, the proposed protocol achieves low energy consumption and longer network lifetime than other popular protocols.
