Evaluation of Power Minimization for Routing Protocol and Multicast Networks

ABSTRACT


INTRODUCTION
Due to nature of wireless channels, wireless communication suffers from multipath fading and the time-varying characteristic that causes distortion to the delivered information. This has imposed a stringent limitation on some applications where retransmission is not possible, such as broadcast/multicast to resolve the problem Joint source channel coding (JSCC) and cooperative transmissions are two classes of solutions that exploit different design dimensions of communication systems.
The advent of wireless mobile ad-hoc networks (MANETs) has offered an efficient and most importantly cost effective technique to make use of the availability of mobile hosts when no fixed infrastructure is provided. In MANET the mobile nodes can easily communicate with each other while they are freely moving around in different directions.
An ad-hoc network relies entirely on nodes cooperation for forwarding information from data sources to intended destination nodes. Some examples of mobile nodes in an ad-hoc network are laptop computers, smart phones and personal digital assistants that interact directly with each other. There are many advantages of such an ad-hoc network which include fast deployment, robustness, efficiency and natural support for mobility. Genetic algorithms based enhanced K Strange points clustering algorithm is also describes that [1]. Media Access Delay and Throughput Analysis of Voice Codec with Silence Suppression on Wireless Ad Hoc Network explained in [2]. An Heterogeneous Population-Based Genetic Algorithm for Data Clustering is described here. The optimal clusters are achieved by modifying the genetic algorithm [3].

PROPOSED SYSTEM
Introduce an asynchronous multi-relay aided two-slot JSCC multicast protocol that can deal with successively refined sources of arbitrary numbers of layers, in which the optimal DFE receiver and the optimal SINR level of each layer in the relayed phase are jointly considered.
Formulate a suite of optimization problems by taking total energy usage as the target, where the transmit power levels at the BS and relays as well as the power ratio of each layer are jointly determined.
Develop a sequential quadratic program through power parameters optimization and a heuristic algorithm to optimally select relays in transmission to further minimize the total power consumption to reduce the calculation complication a heuristic algorithm for communicate selection is obtainable.

DISCUSSION
Asynchronous multi-relay aided two-slot JSCC multicast protocol is proposed and their lifetime is calculated. Optimization problems is formulated by taking total energy usage as the target, where the transmit power levels at the BS and relays as well as the power ratio of each layer are jointly determined. Multi-relay aided two-slot JSCC multicast protocol is obtained and the results are compared with their conventional method. Figure 1

CONCLUSION
The paper considered a multi-relay aided joint source-channel coding (JSCC) multicast network containing a source multiple decode-and-forward relays and multiple destination nodes. Due to the difficulty in synchronizing the relay communication an asynchronous JSCC two-slot multicast protocol was introduced along with an optimal DFE structure where the associated SINR of all layers can be determined based on MMSE criterion. EED at the end nodes was taken as the performance metric for the system optimization subject to the power level and power ratio assigned to each layer at the transmitters. An optimization problem to minimize total influence utilization was formulate and solved where the transmit power level power assigning ratio for all layers, and relay selection can be jointly strong-minded.
