Adaptive Distributed Dynamic Channel Allocation for Wireless Networks
Channel allocation schemes in a mobile computing (wireless) environment can be either static or dynamic. Static allocation offers negligible channel acquisition time and zero message complexity and works well at a low system load; the performance steadily decreases as system load increases since many calls are dropped; in case of even temporary hot spots many calls may be dropped by a heavily l...
متن کاملDistributed Adaptive Channel Allocation in Multi-Radio Wireless Sensor Networks
—To solve the problem of channel allocation in multi-radio Wireless Sensor Networks (WSNs), this paper proposed distributed channel allocation and adaptive update scheme based on channel utilization and Data Transmission Success Rate (DTSR). First, node periodically calculates the channel utilization and DTSR on each data channel. Second, node can adaptively adjust the statistical period and u...

متن کاملDistributed Channel Allocation Scheme for Wireless Sensor Networks
This paper introduces a distributed channel assignment scheme (DCA) for wireless sensor networks. Recent developments in sensor technology, as seen in Berkeley's Mica2 Mote, Rockwell's WINS nodes and the IEEE 802.15.4 Zigbee, have enabled support for single-transceiver, multi-channel communication. DCA exploits this capability by assigning optimally minimum channels in a distributed manner in o...
متن کاملDistributed Channel Allocation Algorithms for Wireless Sensor Networks
Interference between concurrent transmissions can cause severe performance degradation in wireless sensor networks (WSNs). While multiple channels available in WSN technology such as IEEE 802.15.4 can be exploited to mitigate interference, channel allocation can have a significant impact on the performance of multi-channel communication. This paper proposes a set of distributed algorithms for n...
