An Effective Congestion Control Approach through Route Delay Estimation Using Packet Loss in Wireless Sensor Network

Abstract

In wireless sensor networks, congestion control and efficient routing are in much needed due to the increase in the usage of sensor devices in the diverse applications. Even in the randomness in the mobility of the devices creates dynamic topology which causes delay or packet loss in routing. The occurrence of congestion mostly due to the high volume of traffic inflow and low outflow of the data rate. This change in transmission rate results in routing delays and reduced throughput. The rate control is the major concern in applications performing regular streaming, particularly in wireless networks. This paper aims to propose an efficient Congestion Control approach through Route Delay Estimation (CC-RDE) using packet loss to control data rate for effective to minimize the packet loss during congestion. The CC-RDE mechanism will present an illustration for Delay Recognition (DR) and a method for Routing Delay Estimation (RDE) to improve the throughput and reduce the routing delay. The experiment evaluation is performed over a reactive routing protocol to improvise the throughput and reduce delay and energy consumption in comparison with other protocols.
