Interference mitigation and optimal hop distance measurement in distributed homogenous nodes over wireless sensor network

Wireless Sensor Networks (WSN) is in large use in today’s world against the challenges encountered in the Sensor world. Energy consumption, routing, interference mitigation are a matter of concern in WSN. Perhaps, overruling interference mitigation would solve a number of interconnected problems in WSN. The proposed work is narrowed down to minimize interference in distributed homogenous WSN, ensuring that all the nodes in the network operate with the same transmission power. In this paper, an optimal shortest distance algorithm, Dynamic-Optimal Shortest Path Algorithm (DOSPA) is proposed to identify the shortest path in communication between point to point nodes. As the data traverses a number of intermediary nodes, a privileged network topology has to be built to ensure proper transmission of data. An ideal network topology is hence built dynamically for data transmission. However, a collision between data packets in interconnecting nodes is likely to occur. Furthermore, to minimize collision a non-persistent round-robin CSMA/CD algorithm is proposed. We study the network throughput, packet delay, corruption ratio by increasing the number of nodes and hence also analyzing the system in saturation state. It’s found that Packet Corruption Ratio (PCR) with CSMA+DOSPA is minimized compared to CSMA. Thus, interference reduction in distributed homogenous nodes is substantially minimized.
