Enhanced routing in interest centric mobile Ad hoc Network using Random early Detection

Abstract

This paper represents the variation in Mobile Adhoc Network which we called interest centric mobile ad-hoc network or (Radnet) in terms of prefixes, application interests and also talks about RED at gateways to avoid congestion by Calculating the average queue size. Each network device has buffer for keeping incoming packet if packet is not immediately transferred, keep packets if imitative space is available and drop packets if imitative space is exhausted. Mobile ad hoc Network (MANET) devices also using imitative space for same purpose as other network devices. Most MANET devices uses Drop Tail queue in which packets are accepted till the queue is empty and starts dropping all incoming packets when queue becomes full. Retransmission of lost data packets needs resource consumption (i.e. battery power and link bandwidth) which is critical in MANET. Drop tail queue suffer the issue of global Synchronization. RED uses a technique called, early detection of packet drop without waiting to queue get overflow, this technique notify the sender to slow down reduce the packet sending rate and also inform the receiver to not to send acknowledgement packets. To evaluate the effectiveness of Radnets for generating lower disturbance in communication medium and to reduce the message overheads, we are adopting this RED scheme.
