Abstract

Wireless sensor networks are appearing as an emerging need for mankind. Though, Such networks are still in research phase however, they have high potential to be applied in almost every field of life. Lots of research is done and a lot more is awaiting to be standardized. In this work, cluster based routing in wireless sensor networks is studied precisely. Further, we modify one of the most prominent wireless sensor network's routing protocol "LEACH" as modified LEACH (MODLEACH) by introducing efficient cluster head replacement scheme and dual transmitting power levels. Our modified LEACH, in comparison with LEACH out performs it using metrics of cluster head formation, through put and network life. Afterwards, hard and soft thresholds are implemented on modified LEACH (MODLEACH) that boast the performance even more. Finally a brief performance analysis of LEACH, Modified LEACH (MODLEACH), MODLEACH with hard threshold (MODLEACHHT) and MODLEACH with soft threshold (MODLEACHST) is undertaken considering metrics of throughput, network life and cluster head replacements.

MODLEACH:用于无线传感器网络的LEACH的一种变体

无线传感器网络作为人类的新兴需求而出现。虽然这种网络还处于研究阶段，但它在生活的各个领域都有很大的应用潜力。很多研究已经完成，还有很多有待标准化。本文对无线传感器网络中基于集群的路由问题进行了详细的研究。此外，我们通过引入高效簇头替换方案和双发射功率级别，将目前最著名的无线传感器网络路由协议“LEACH”修改为改进的LEACH (MODLEACH)。与LEACH out相比，我们改进的LEACH使用簇头形成、put和网络寿命的度量来执行它。然后，在改进后的LEACH (MODLEACH)上实现了硬阈值和软阈值，使性能更加优越。最后，考虑吞吐量、网络寿命和簇头替换等指标，对LEACH、改进LEACH (MODLEACH)、硬阈值MODLEACH (MODLEACHHT)和软阈值MODLEACH (MODLEACHST)进行了简要的性能分析。
