Packet Aggregation in TelosB WSNs: Design, Implementation and Experiments

Abstract

WSN is an extensive field of research and a core technology which is adopted for monitoring and data assembling, used in various applications. Traditionally in a WSN, communication is performed in the fashion of single packet per transmission which produces high energy consumption and longer delay. Therefore, we introduce a novel approach by designing a system which applies packet aggregation in TelosB sensor motes using Contiki platform. In this approach, we assemble multiple packets together and send them in an aggregated frame towards the sink which can reduce the number of transmissions, energy consumption and delay per transmission unit. Accordingly, in this thesis report, we perform aggregation at relay node with diverse set of topologies and schemes and examined this technique through numerous experiments and testing for temporal and spatial aggregation topologies. Additionally, we design and implement three packet aggregation schemes and perform a comprehensive set of experiments to evaluate these schemes. These experiments are capable to demonstrate how packet aggregation proposes compelling performance boost in terms of less transmission count and how these schemes strongly actuate the energy level due to the reduction in transmission count. This report concludes with a brief summary of these experiments and recommends some potential approaches to affirm and further expand these outcomes. We have a belief that this research will be effective for better understanding of packet aggregation approach in WSN for future pioneers.
