Priority Toning Strategy for Fast Emergency Notification in IEEE 802.15.4 LR-WPAN

چکیده
IEEE 802.15.4 Low Rate Wireless Personal Area Network (LR-WPAN) is developed for emerging applications for industrial automation, home networking, wireless sensor networks, etc. In this paper, we propose a new scheme to enhance IEEE 802.15.4 in order to enable the fast delivery of packets, which announce the emergent situations or events of the network. With the parameter tuning of the legacy IEEE 802.15.4 slotted Carrier-Sense Multiple Access with Collision Avoidance (CSMA-CA), we enhance the current CSMA-CA algorithm by adopting a Priority Toning strategy. Through the simulations, we validate that our scheme is very efficient in the context of energy consumption as well as delay without system throughput degradation. This research was supported by University IT Research Center Project.

Service Differentiation based on Contention Window with Enhanced Collision Resolution LR-WPANs
The IEEE 802.15.4 MAC [1] standard defines the channel access for low-rate, low-power communication applications such as Wireless Sensor Networks but does not differentiate between high or low priority data. We study few priority based service differentiation mechanisms which distinguish between such data for each and every device, and also let high priority have better channel access as compar...
متن کاملA Improved Channel Access Algorithm for IEEE 802.15.4 WPAN
The IEEE 802.15.4 standard is able to achieve low power transmissions in low-rate and short-distance wireless personal area network (WPAN). The CSMA/CA algorithm is used for contention mechanism that collision and retransmission occur. If a collision occurs, CSMA/CA algorithm executes retransmission operation. So it’s very important to decrease retransmission count. In this paper, we propose a ...
متن کاملPerformance Evaluation on IEEE 802.15.4 Scatternet Sensor Networks
LR-WPAN networks are equipped with battery-powered sensors and changing batteries is considered impractical. Therefore, energy saving is very important when building such networks. IEEE 802.15.4 is a standard for LR-WPAN, which specifies the Physical layer and MAC layer for LR-WPAN. Scatternet is a network structure where sensors are grouped into clusters using star topology piconets. Each pico...

IEEE 802.15.4 is the Low-Rate Wireless Personal Area Network (LR-WPAN) standard that is suitable for wireless sensor networks and wireless home networks among others. The IEEE 802.15.4 is specifically designed for energy efficiency since many 802.15.4-compliant devices are expected to operate on battery. Because of inadequate design of the downlink frame transmission mechanism in the standard, ...
