Performance Analysis of large scale ZigBee network design through geometric structure

Wireless Sensor Network (WSN) is a group of the specialized wireless devices which forms a communication infrastructure at a diverse location. IEEE 802.15.4 standard for wireless devices like ZigBee has demonstrated its enormous application as WSN. ZigBee has got popularity for its both small range and wide range coverage. In wide range coverage, a large scale ZigBee network deployment is going ahead. Without proper network structure, a lot of sensor nodes needed for coverage. And also take down the network performance of the large-scale ZigBee network. This study, however, carries a new geometric structure to improve the formation of large scale ZigBee network and its performance. The network simulator Riverbed is used to design and implement a large ZigBee network in geometrical patterns. And also the network performance is analyzed by scrutinizing different network parameters. For real-time communication, free from network path is chosen according to the traffic inside the network. Finally, a deep analysis between two geometric structures - random and octagonal has presented with related parametric aspects. The analysis indicates the new octagonal structure shows significant performance in large scale ZigBee network deployment. This study will create a new opportunity to establish a reliable large-scale ZigBee network.

I. Introduction

ZigBee is a standard wireless sensor device to form a perfectly interoperable sensor network. ZigBee is the standard network protocol base solely conducted under the ZigBee Alliance. IEEE 802.15.4 standard initializes the ZigBee as the standard of the wireless network. IEEE 802.15.4 defines the physical layer under network and application layer of the ZigBee network. ZigBee has splendid features such as low cost, low data rate, high security, green power, low power consumption etc. That draws its global value. ZigBee is used in security, pervasive computing, indoor position monitoring, data gathering, industry, home or office automation etc. From consumer electronics to industrial PC peripherals, ZigBee has the ability to control in various areas of use [1], [2], [3], [4].
