Many-to-one transport results in congestion in wireless sensor networks (WSNs). This is due to the sudden impulse of information flowing to a single destination by single branch. More attention has been paid to congestion control in WSN, but most research works in the past were apt to handle it by controlling output sending rate, and seldom sought solutions on utilizing the idle resources of non-congestion...
In cognitive radio networks, secondary users can implement cooperative spectrum sensing to achieve better performance than single secondary user sensing. However, the accuracy of cooperative sensing can be severely degraded when the report and inter-user channels experience fading in reality. Aiming at solving this problem, we proposed a chain-based OR-rule cooperative spectrum sensing scheme. To...
