Least delay path estimation routing protocol (LDPERP) with enhanced multimedia transmission through parallel links over heterogeneous MANETS

MANETS (Mobile Ad Hoc networks) are a group of wireless mobile nodes without any prefixed infrastructure that can move anywhere breaking and forming the links with the devices. Each node is responsible for routing the packets. Hence, each node acts as a router. A multi rate network allows a higher transmission capacity with wide range and also the signals can be transmitted with different bit rates. Thus there are many constraints concerning with the multi rate network like the data traffic integration, Quality of service and route establishment etc. Heterogeneous MANET'S are the networks with different nodes and different resources. In order to transmit a message the first requirement is to employ a route from end to end with minimum delay. In this paper, we have shown different delays that is involved during packet transmission considering different routes, hops and different rates with necessary mathematical formulations and conditions which proves to be enough for satisfying demands of quality of service (QOS) like discovering a path with minimal time delay. At the same time the other paths needs to be utilized to avoid the data rates to get degraded. For this purpose, Packetizing is used which can increase the efficiency and utility of a network. In our paper, we have proposed an approach that can ensure minimum delay though the routing parameters may differ. This kind of approach has found to be more efficient for the multimedia transmission over heterogeneous networks.
