To improve the network performance, the SDN controller has to choose the shortest and optimised path between source and destination in routine and emergency packet transmission. In e-health service, information of the emergency patient has to be transferred immediately to remote hospitals or doctors by using efficient packet routing approach in Wireless Body Area Network (WBAN). In WBAN, to improve the packet transmission, the optimal packet routing policy developed based on packets priority with the support of a greedy algorithm for SDN. The SDN Controller selects the forwarding node based on node propagation delay and available bandwidth between two forwarding nodes. The mesh network topology network created for implementation, implementation results are compared with existing research works. Finally, this algorithm implemented in our institution, Software defined communicati...

The known location of sensor node helps in determining the event of interest. A mobile sink is introduced to track the event driven sensor nodes in the path of the event, thus conserving energy and time. We present a novel range based localization algorithm which helps the mobile sink to compute the location of the sensor nodes efficiently. The data transfer from the mobile sink and the sensor nodes is used to estimate the sensor location. The sensor nodes do not need to spend energy on neighbouring interaction for localization. The localization mechanism has been implemented in TOSSIM. The simulation results show that our scheme performed better than other range-based schemes.

This perspective makes it interesting to take a look at scenarios where small chips would become so plentiful that this will not only allow identification of relatively valuable single objects but could also be simply distributed over surfaces, like in scenarios emerging from sensor networks research. We introduce a new method for locating objects in a dynamically changing environment. Yet, for instance, RFID tags attached to mobile objects provide us with interesting new applications, like allowing mobile devices to obtain their current location or context information on the spot, without rather expensive positioning calculations. Our modified particle filter algorithm provide better accuracy in locating a dynamically moving object in a Library, where the speed of movement is within specified limits.
