interest in wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion‚ with the end goal of handing their processed data to a base station. Sensing‚ processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications [A1]‚ [A2]. Sensor networks provide

Abstract: Wireless technologies have experienced an enormous growth in the last decades. The wireless personal area networks (WPANs) and wireless local area networks (WPANs) are heterogeneous networks which are used in different applications. Two networks‚ called Wifi (IEEE 802.11 WLAN) and ZigBee (IEEE 802.15.4 WPAN)‚ which operates in 2.4 GHz frequency. Spectrum sharing is an effective technique which is used to enhance spectrum utilization. However the coexistence and Interoperability is a critical

1. INTRODUCTION Communication is always necessary in building relations to mankind‚ when two persons meet they need some medium to interchange their views but due to distance barriers some tools are required to communicate each other. At the end of 19th century‚ reckoned \scientist Graham Bell laid the first stone in the field of communication using different tools regardless of distance. He invented first wired base telephony equipment. It was the solution for the voice communication for the people

Abramson‚ a professor at the University of Hawaii‚ developed the world’s first wireless computer communication network‚ ALOHAnet (operational in 1971)‚ using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. Definition A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio)‚ and usually

graphs we can see that using PCF network resulted in even higher delay in the nodes that does not enable PCF. Furthermore‚ PCF networks reduced the number of retransmission even in the nodes without PCF enabled as PCF networks decrease the collisions and in turn the number of retransmission. Nodes with enabled PCF take the advantage of contention free period as we can see from the drop in both delay and retransmission while nodes gets affected by being in a PCF network while it does not utilize the
