Improved Congestion Control using Modified Red Algorithm over Manet

  Kinjal Vaghela

Manet a mobile ad hoc network is network without any fixed infrastructure [1]. In mobile ad hoc network mobile nodes are freely moved anytime, anywhere without infrastructure that means they are self systematize. In this type network nodes behave as nodes as well as router. Due to mobility and no fixed infrastructure there are various problems arise among them congestion is the major problem in Manet. Congestion is situation where transmitted packets to the network are much more than holding capacity of network. The RED (Random Early detection) is congestion control algorithm [1][2] which is active queue management technique that can avoid congestion. RED is powerful then other traditional algorithms but RED has challenges such as high packet drop ratio, degradation of throughput and frequent link failure. This paper presents the Modified Red algorithm over Manet. Modified Red algorithm is better as it lowers the packet drop at high load and increases the throughput and takes care of underutilized resources. Modified Red with ECN (Explicit Congestion Notification) can be better in performance than red without ECN. So I am trying to modified red with ECN.
