In such layer and transport layer. This paper proposes a style networks, TCP-supported congestion manage has been approach, deviating from the normal network style, toward unreliable the standard transport protocols like UDP enhancing the cross layer interaction. Among completely are a unit unreliable, since no mechanism of different layers specifically physical, mac and network. The congestion detection has been provided. Even Cross Layer style approach for Power manage (CLPC). supported control is unreliable . Transmission powerWould facilitate to boost the transmission power by related issues will have an effect on all the layers of the averaging the RSS values and to search out a good route stack, from physical to move, and include the following: between the supply and therefore the destination. This (i) long delay, (ii) packet losses and (iii) low output. cross-layer style approach was tested by simulation (NS2 Previously, the look of ad hoc network protocol has simulator) and its performance over AODV was found to beenlargely supported the‘‘layeredapproach’’.In layere be higher. d architecture,the designer or implementers of the protocol or algorithmic rule focuses on a selected 1. INTRODUCTION layer, while not being needed to contem plate the A mobile ad hoc network could be a collection of parameters of the remainder of the stack . However, wireless nodes that can transfer information while this has usually resulted in suboptimal performance of not the utilization of network infrastructure or applications. To overcome this, the ‘‘cross-layer’ administration. Such networks have several potential ’approach has been found to deal with transmission applications, as well as in disaster mitigation, defense, power related problems in wireless ad hoc networks. health care, domain and business. In such a network The cross layer style deviates from the normal network , every node acts each as a number and a router. a design approach during which every layer of the stack significant limitation with mobile nodes is that they would be created to work severally .A work group of need high mobility, inflicting links to be the Internet Engineering Task Force has been learning frequently broke and reestablished Moreover, inter-layer interactions and performances in mobile ad the bandwidth of a wireless channel is additionally hoc networks. The inter-layer interaction metrics and limited, and nodes operate restricted batter power also the advantages of information exchange among ,which will eventually be exhausted. Therefore, the the lower layers, network layer and transport layer planning of a mobile ad hoc network is were additionally reported. In this paper, a brand extremely difficult, however this technology has high new cross layer optimization frame work is proposed prospects to be able to manage communication that gathers info a few node’s receiver signal strength protocols of the future .A wireless ad hoc network (RSS) by using hello packet. Employing a dynamic works on the principle of one hop neighbor node transmission power manage mechanism, each node broadcasting, during which a transmission signal from computes minimum RSS, average RSS and most RSS. the source node propagates to all neighbor nodes This info can facilitate every node to understand its within its communication region Transmission power neighbor positions and guide it to dynamically related problems are a unit a manage its power levels.
