Storage node based routing protocol for Wireless Sensor Networks

Abstract

Efficient routing is a key concern for the execution of high performance query processing in Wireless Sensor Networks (WSN). Existing routing protocols lack the efficiency in terms of energy consumption, accuracy and timing response. Data storage and processing constraints in sensor nodes also hinder the efficient and timely response in various applications, especially in healthcare, where, many vital data are collected from the patients using wireless devices. These data can be crucial for saving the patient's life. Thus, an efficient, accurate and fast routing protocol is of utmost importance in healthcare. Present routing protocols in hierarchical network protocols, the cluster heads are selected from general sensor nodes, however the storage and processing constraints perceive in the usual wireless biomedical sensors as the processing requires more energy consumption and the storage capacity is limited. In this paper we propose a novel routing protocol by utilizing Storage nodes. We evaluate and prove the feasibility of the proposed protocol through extensive simulations. Simulation results show that the protocol is more energy efficient, faster and data resilient compared to other techniques.
