Wireless sensor networks applications involve a position of inaccessible m.tropolitan vicinity en-closed by wireless sensor nodes (WSNs)-m.nitors environm.ntal param.ters like battle field surveillance, hom. applications like fire alarm. health m.nitoring, etc. Energy plays a vital role in Wireless sensor networks. So, we have to concentrate m.re on balanced energy consum.tion for m.xim.zing the network lifetim.. m.nim.zing the whole network overhead and vigor disbursem.nt coupled with the m.lti-hop data reclam.tion process that ensuring balanced energy consum.tion am.ng SNs which results in prolonged network lifetim.. This can be achieved by forwarding the sensed data to their cluster heads and then filtering the data before sending it to their tryst nodes, which is located in proxim.ty to m.’s trajectory. Sleep and awakening of nodes periodically helps to retain their energy for som. m.re tim.. The events occurring in any part of the network should be identified by the nodes, while arrangem.nts sleep and active am.ng the nodes. (i.e.) the nodes should be scheduled to sleep, so that the outstanding nodes can take care of the whole network. The eXtensible Random.zed m.trix Arithm.tic Coding (XRm.C) Technique has been used to enhance the security am.ng all the nodes in the network. Sim.lation results show that our Proposed Schem. can have better Lifetim., im.roved throughput, reduced delay com.ared to other existing m.thods.

m.bile Ad Hoc Network is a self-configuring, autonom.us, infrastructure less network of m.vable nodes which will be autom.tically connected by wireless connection with no access point. The nodes are free to m.ve anywhere in the set of connections and the topology of m.NET rem.ins unpredictable. The m.jor com.lexity with the available two hop relay protocols in m.NET environm.nt is to achieve the optim.zed throughput with reduced packet delivery delay. A generalized collection based two-hop relay and redundancy of the packet is used to attain the reduced delay. The com.lex process of packet delivery in m.NET utilizes Routine Response Control and m.dified m.rkov chain m.del. Tuning carefully the param.ters, the transm.ssion range, the packet redundancy and the group size help to achieve the optim.zed throughput with the reduced packet delivery delay. Transm.ssion power of a node is controlled which helps in achieving the optim.zed throughput and reduced delay.

m.stly, cloud agreem.nts are signed between the consum.r and the provider using online click-through agreem.nts. Several issues and conflicts exist in the negotiation of cloud agreem.nt term. due to the legal and am.iguous term. in Service Level Agreem.nts (SLA). Sem.ntic knowledge applied during the form.tion and negotiation of SLA can overcom. these issues. Cloud SLA negotiation consists of num.rous activities such as form.tion of SLA tem.lates, publishing it in registry, verification and validation of SLA, m.nitoring for violation, logging and reporting and term.nation. Though these activities are interleaved with each other, sem.ntic synchronization is still lacking. To overcom. this, a novel SLA life cycle using sem.ntic knowledge to autom.te the cloud negotiation has been form.lated. Sem.ntic web platform.using ontologies is designed, developed and evaluated. The resultant platform.increases the task efficiency of the consum.r and the provider during negotiation. Precision and recall scores for Software as a Service (SaaS), Platform.as a Service (PaaS) and Infrastructure as a Service (IaaS) SLAs were calculated. And it reveals that applying sem.ntic knowledge helps the extraction of m.aningful answers from.the cloud actors.

Advances in VLSI technology have enabled the im.lem.ntation of com.lex digital circuits in a single chip, reducing system.size and power consum.tion. In deep subm.cron low power Cm.S VLSI design, the m.in cause of energy dissipation is charging and discharging of internal node capacitances due to transition activity. Transition activity is one of the m.jor factors that also affect the dynam.c power dissipation. This paper proposes power reduction analyzed through algorithm.and logic circuit levels. In algorithm.level the key aspect of reducing power dissipation is by m.nim.zing transition activity and is achieved by introducing a data coding technique. So a novel m.lti coding technique is introduced to im.rove the efficiency of transition activity up to 52.3% on the bus lines, which will autom.tically reduce the dynam.c power dissipation. In addition, 1 bit full adders are introduced in the Ham.ing distance estim.tor block, which reduces the device count. This coding m.thod is im.lem.nted using Verilog HDL. The overall perform.nce is analyzed by using m.delsim.and Xilinx Tools. In total 38.2% power saving capability is achieved com.ared to other existing m.thods.
