Long Range for Communication in Wireless Sensor Networks

Abstract

In this project research work has been conducted for comparison of MAC layers of both 802.11e and 802.16e. More specifically Quality of service and reliability issues of both the protocol standards are compared, with the help of simulations. 802.11e and 802.16e are compared because they are only available standards that provide built-in quality of service and mobility. This comparison is done for a doctor patient application where patients have sensors which communicate with the base station located at the hospital. Sensors are used for the transmission of patient‟s condition at any instant of time. So starting from the MAC layer issues of both WiMAX and WiFi, future work can be conducted on physical layer so that pros and cons for enabling WiMAX protocol for WSN can be discovered.
