This paper presents the throughput results obtained from a Wireless Sensor Network testbed, with single and multiple sources in different network deployments and routing architectures. The experimental testbed deployed at IIT Madras consisted of commercially available Crossbow TelosB and MicaZ nodes and a custom-built sensor node based on the DigiNet Xbee chip, with all nodes implementing the Zigbee standard. The networks were deployed in uniform grid topologies in three different deployments with up to 228 nodes. The main aim of the experiments is to analyze the throughput and packet delivery ratio observed with single and multiple sources. The experimental results show that delivery ratio reduces with increase in data rate due to collisions and help characterise the network capacity limits. © 2012 IEEE.

Testbed based throughput analysis in a Wireless Sensor Network

2012 National Conference on Communications, NCC 2012

This paper presents an implementation based study of multi-channel medium access control protocols in hardware constrained wireless sensor network(WSN) nodes with 802.15.4 radio. In the network architecture presented, each sensor node has a single radio transceiver that can be tuned to any of the available sixteen non-overlapping channels. The simplest way to select data channel is to use a common channel signaling between the nodes. We have conducted experiments to verify whether control channel congestion can occur in case of 802.15.4 radios using MicaZ and TelosB motes. The throughput results show the per-node throughput does not decline as significantly with increasing number of senders, with the proposed multi-channel protocol. ©2009 IEEE.

Low Power Communication Protocols: ZigBee, 6LoWPAN and ZigBee IP

Designing a multi-hop wireless network is a challenge mainly because of high bit error rates and the inherent broadcast nature of the medium creating interference. To improve the capacity, protocols based on spatial reuse of frequencies with multiple orthogonal channels have been introduced. This is particularly useful in complete wireless environments such as wireless mesh networks and wireless sensor networks (WSN). Based on initial testbed experiments on WSN testbeds, we show that there is a gap between reality and simulation models due to overheads in implementing these protocols. In order to support QoS guarantees in critical paths for such networks, we present a generic channel allocation scheme based on k-distance coloring problem, for multiple channel networks. The scheme is designed keeping in mind the real time deployment issues in wireless networks. We report the results from experiments conducted using a IEEE 802.15.4 based testbed consisting of Xbow MicaZ nodes and results obtained using the OMNET4 simulation environment. © 2010 IEEE.
