In this paper, we address the beacon congestion issue in Vehicular Ad Hoc Networks (VANETs) due to its devastating impact on the performance of ITS applications. The periodic beacon broadcast may consume a large part of the available bandwidth leading to an increasing number of collisions among MAC frames, especially in case of high vehicular density. This will severely affect the performance of the...
In this paper, a differentiated services based congestion control algorithm for Wireless Multimedia Sensor Networks (WMSNs) is proposed. Keeping in mind the characteristics of Wireless Sensor Networks (WSNs) and their possible extensions, the proposed algorithm categorizes WMSNs traffic into six different classes. The algorithm takes a novel and different approach towards congestion control in WMSNs...
Although TCP is one of the key protocols of the Internet infrastructure, it is not optimized for either wireless environment or multimedia streaming applications. It fails to meet the service requirement of streaming applications because of its strict adherence to congestion control. Besides, non-congestion packet loss fools TCP to slow down its sending rate over wireless links. Fast TCP and TCP Westwood+...
