A Survey on Congestion Control Routing for Wireless Network
نویسنده
چکیده
Wireless networks have long suffered from congestion. It occurs when source node transmits the data at a rate greater than that of a network device can accommodate. It causes the buffer on such devices to fill up and possibly overflow. It results in loss of packets. Most of the Routing protocols which are currently in use are not congestion Adaptive. Existing congestion control schemes treat congestion as an individual problem and propose ad hoc solution that is dissatisfied. Routing should not be aware of, but also be adaptive to network congestion. Adaptation to the congestion helps to increase both the effectiveness and efficiency of routing. These problems are solved by the congestion-aware routing protocols in certain degree. These protocols which are adaptive to congestion status of mobile ad-hoc network can greatly improve the network performance. Further it allows a network to operate in the region of low delay and high throughput. This survey paper concentrates on congestion detection and congestion

This paper proposes an efficient network architecture to improve energy consumption in Wireless Sensor Networks (WSN). The proposed architecture uses a mobile data collector to a partitioned network. The mobile data collector moves to center of each logical partition after each decision period. The mobile data collector must declare its new location by packet broadcasting to all sensor node...
