Abstract

Mobile Adhoc Network consists of petite sensor nodes with sensing, working out and wireless communication capabilities. Now a day, it is discovery wide applicability and increasing deployment, as it enables reliable monitoring and psychoanalysis of location. The design of routing protocols for MANET is influenced by many challenging factors like fault tolerance, energy efficiency, scalability, latency, power consumption and network topology. In this paper, focused on minimizing end to end latency and energy efficiency as primary design objectives of routing protocols for MANET without overshadowing the other design factors which can be present a survey of low latency, energy efficient and time critical routing protocols. Markov chain-based framework protocol, a reactive network protocol which is well suited for time critical data sensing applications is quite efficient in terms of energy consumption and response time. This is a hybrid network protocol which gives the overall picture of the network at periodic intervals in a very energy efficient manner. This is a Stateless, highly efficient and scalable protocol for sensor networks which achieves end to end soft real time communication by maintaining a desired delivery speed across the network through a novel combination of feedback control and non deterministic geographic forwarding.

Abstract

To provide an efficient QoS routing communication in MANET in a secure way, we implement an enhancing security and QoS routing in MANET by adapting optimization technique of Ant Colony Optimization with Fairness Index and the security of MANET for data communication is achieved by using Group Key management with self assessment key. This stimulates us to consider both security and QoS routing together in ad hoc scenario for both routing and message/data communication. To improve the secure data communication in MANET, we present a routing based data security using group key management based on self assessment key. The nodes in the network will creates its own key (self assessment key) based on the group which has maintains its unique key before it has been joined into the network for data communication security to recover the node reputation on receiving the data or sending the data to and from other mobile nodes. An experimental evaluation is done to estimate the performance of the proposed enhancing security and QoS routing using group self assessment key [ESQR] in MANET in terms of energy, throughput, and network lifetime.
