Increasing Quality of Service (QoS) in Wireless Sensor Networks (WSN) by Using Timestamp Optimization Scheme

In this paper, we study various factors affecting the Quality of Service (QoS) of wireless sensor networks (WSNs) including the current research and the future directions.This paper presents a new Timestamp Optimization Technique to improve and maintain the QoS in WSN.To describe the proposed scheme, both analytical and mathematical models are presented.Assumptions are made for applicability of the scheme in networks.For instance, the proposed scheme formulizes the given scenario by considering only the sensor nodes that are one-hop distant to the sink node.
