Enhanced QoS Mechanism using Mobile Agents in Wireless Sensor Networks

Abstract- Wireless Sensor Networks can be used for a wide range of battlefield applications such as target tracking and emergency response. These networks have some specific types of requirements, such as diverse real time requirements, diverse reliability requirements and mixture of periodic and a periodic data. QoS is a challenging problem due to dynamic topology change, large data transfer and unreliable wireless link in wireless sensor networks. We have introduced a new protocol, which provides enhanced QoS mechanism in terms of high reliability, less latency and reduced power consumption through a probabilistic approach, which improves the lifetime of a wireless sensor as a trust ware. Mobile agents are used for automation and dynamism to the adaptation of software in wireless sensor networks. The novel approach provides enhanced QoS mechanism through dynamic software to guide the system adaptation. Mobile agents are used to form adaptation feedback on to the running system. Thus our approach is a complimentary over all other existing systems in this area
