TAILIEUCHUNG - Inter-cluster communication in wireless sensor networks

This paper highlights the distinction between cluster merging and cluster diffusion, presents architecture for carrying out efficient diffusion and finally compares these two approaches under various network conditions. Simulations are carried out in Network Simulator (NS2) which shows that cluster diffusion can be rendered efficient when multiple edge nodes are used for inter-cluster communication. | International Journal of Computer Networks and Communications Security VOL. 5, NO. 1, JANUARY 2017, 1–6 Available online at: E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) Inter-Cluster Communication in Wireless Sensor Networks SAIMA ZAFAR1 and ALI HAMMAD AKBAR2 1 Department of Electrical Engineering, National University of Computer & Emerging Sciences, Lahore, Pakistan 2 Department of Computer Science, University of Engineering and Technology, Lahore, Pakistan 1 saima_zafar@, 2ahakbar@ ABSTRACT Wireless Sensor Network (WSN) comprises of end devices or nodes equipped with sensors, microcontrollers and transceivers that communicate wirelessly to accomplish goals like surveillance, monitoring and control etc. Groups of nodes under the control of a single cluster head form clusters. Communication within WSN clusters is a widely researched area, however communication among multiple clusters located in close proximity is challenging due to clusters operating in distinct logical channels. Cluster merging and cluster diffusion are proposed for inter-cluster communication. In merging the two clusters combine to form a single network while in diffusion the two clusters are expected to retain their individuality while diffusing through edge nodes. This paper highlights the distinction between cluster merging and cluster diffusion, presents architecture for carrying out efficient diffusion and finally compares these two approaches under various network conditions. Simulations are carried out in Network Simulator (NS2) which shows that cluster diffusion can be rendered efficient when multiple edge nodes are used for inter-cluster communication. Keywords: Sensor Networks, Network Cluster, Cluster Merging, Cluster Diffusion, Sensor Nodes. 1 INTRODUCTION This [1] standard supports ubiquitous computing like wireless sensor networks. WSN are distinguished by features such as low cost, low power, low speed, short range, small
