Optimization Techniques for Wireless Sensor Networks

Wireless sensor networks (WSNs) deal with the major issue of energy limitation in their deployments. In this paper, we will discuss the quality of service (QoS) parameters considered when designing an infrastructure for optimal energy efficiency in a wireless sensor network. There are several issues that constrain the WSNs and challenges posed by the environment of handling traffic and the lifetime of the battery in the nodes. We discuss the different techniques proposed by current studies used to deal with these challenges. We briefly illustrate different factors and aspects to evaluate the value each optimization technique provides from scalability to reliability. Finally, we designed an algorithm that reduces the amount of data traffic and satisfies the QoS requirements and further propose a technique that alleviates the unbalanced energy usage, data redundancy and prolong the effective system lifetime.
