Energy stability is considered as the core challenge of Wireless Sensor Networks (WSNs) as it is the main factor that contributes towards improved network lifetime expectancy. Clustering with maximized energy efficiency is determined to be the well documented NP hard optimization solution that has the possibility of resulting in prolonged network lifetime. Diversified number of computational approaches that includes nature inspired metaheuristic algorithms, reinforcement schemes and evolutionary algorithms were used for attaining efficient clustering process in WSNs. In this paper, Red Deer and Simulation Annealing Optimization Algorithm-based Energy Efficient Clustering Protocol (RDSAOA-EECP) is proposed for improving lifetime expectancy and energy stability in WSNs. This clustering protocol is proposed with the global optimization capability of the red deer optimization algorithm and local optimization potential of simulation annealing. In specific, RDA is used for diversification and Simulated Annealing (SA) for intensification in order to establish balance between them during the clustering process in order to sustain energy stability. This RDSAOA-EECP protocol is proposed with SA as the search tool that prevents the phases of fighting and roaring phases of RDA involved in the intensification process. Moreover, this clustering protocol inherits the potentialities of the proposed metaheuristic properties in order to achieve optimal cluster heads together with the optimal base station location for the objective of enhancing energy efficiency. The simulation results of the proposed RDSAOA-EECP protocol guaranteed its potentiality over the baseline clustering approaches in improving network lifetime, throughput, packet deliver rate with minimized network latency and energy consumptions independent to the homogeneous and heterogeneous sensor network setup considered for implementation.

ABSTRACT:-Index Terms-Identity-based cryptography,proxy public key cryptography, remote data integrity checking. 1.INTRODUCTIONNear the expedient advance of picking and correspondence structure, a significant measure of information are passed on. These giant information needs more solid figuring asset and more real storage room. All through the most recent years, passed on figuring fulfills the application essentials and winds up being rapidly. On a unimaginably imperative level, it takes the information organizing as a relationship, for example, stockpiling, figuring, information security, et cetera. By utilizing the general pack cloud sort out, the customers are reduced of the weight for most ousted point alliance, broad information access with free land zones, et c. As much of the time as conceivable widening number of customers may need to store and process their information by utilizing the remote spilled choosing structure.With no endeavor at being immediate circumnavigated picking, the customers store their goliath information in the remote open cloud servers. Since the set away information is outside of the control of the customers, it joins the security perils like secret, hanging on quality and responsiveness of information and affiliation. Remote information faithful quality checking is a primitive which can be utilized to affect the cloud customers that their information are kept set up. In some weighty cases, the information proprietor might be compelled to find the opportunity to people all around cloud server, the information proprietor will dispense the errand of information managing and trading to the untouchable, for instance the delegate. On the pivot side, the remote information uprightness checking custom must be significant reviewing the veritable concentration to make it fitting for most grand obliged end contraptions. Therefore, in setting of character based open cryptography and delegate open key cryptography, we will consider ID-PUIC custom.Clearly cloud condition, most customers trade their information to PCS and check their remote information's devotion by Internet. Right when the customer is an individual
