چکیده
This paper presents the throughput comparison at the fully functional device and reduced functional devices of IEEE 802.15.4 with different modulation schemes for Wireless Sensor Networks (WSNs). From the simulations it is revealed that Minimum Shift Keying (MSK) is best suited for all types of devices in 802.15.4 for wireless sensor networks if throughput is to be maximized. Simulations also reveal that Quadrature Amplitude Modulation of 64 bits (QAM_64) at the radio receiver and Personal Area Network (PAN) coordinator of radio transmitter while Binary Phase Shift Keying (BPSK) at the end devices of radio transmitter are unsuitable if throughput is to be considered. Overall it is revealed that there is trade off for using various modulation schemes on the basis of throughput for different types of devices in IEEE 802.15.4 for WSNs

An Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...
