Cloud Computing is a major area of research. Cost and Load balancing has become an important QoS parameter. Load Balancing directly affects the Reliability, Response Time, Throughput and Energy Efficiency of a Server. A good Load Balanced architecture implies minimized overall time, less server failure, minimized response time, increased throughput and less wastage of energy. Such architecture also...
The era of cloud based multimedia applications has lead to a huge increase in the no. of requests on cloud. The increased no. of requests on cloud leads to an increased workload, making workload balancing an important QoS Parameter. Workload Balancing also leads to a judicious use of resources like electricity etc. and thus promotes the concept of Green IT. The paper presents a new Load Balanced Resource...
In this paper, a modified S-MAC protocol incorporating a new back-off mechanism applicable to body sensor networks (BSNs) is proposed. The proposed protocol alleviates the drawback associated with the back-off mechanism which is currently utilized in the original S-MAC protocol in addition to its derivatives. Also, the cross-layer technique is used so as to achieve a better energy consumption and...
Cognitive radio technology can enhance spectrum usability by allowing secondary users to opportunistically access unused or under-utilized frequency bands. Although a number of ideas have been proposed for improving the performance of cognitive radio networks, but slight attention has been given to the selection of reliable data channel(s) and energy efficiency at MAC layer. In this paper, a novel...
In this paper a switch-stay model is proposed for spectrum access by a secondary user in the presence of a primary user, which considers the impact of spectrum handoff delay. This model is then studied to balance the trade-off between the secondary user's energy efficiency and transmission reliability in light of the probability of collision, throughput and delay constraints. Bounds on the probability...
Routing is a major challenge in sensor networks, due to constrained resources of energy, processing power, and memory. This proves that there is an urgent need to design energy efficient routing protocols for sensor networks for prolonging network lifetime. This paper presents a new beaconless multihop routing algorithm (BMR) for wireless sensor networks which is light weight, energy efficient and...
Lightweight Congestion Aware Reliable Transport protocol (LCART) is based on cross-layering the prevalent or reciprocal functionalities of Transport, MAC and Wireless-Physical layers in order to achieve energy efficiency and meeting QoS objectives of heterogeneous WSN1 including multimedia. LCART intelligently overcomes network congestion by the simultaneous use of Packet Service Time, Packet Inter...
In this paper, we present a novel energy efficient routing protocol for wireless sensor networks in which the sensor nodes as well as the base station are mobile. The protocol is hierarchical and cluster based from network structure perspective. Each cluster contains one cluster head node and two deputy cluster head nodes. The re-clustering time and energy has been minimized by introducing the concept...
With the increasing concern for global warming, the impact of Internet power consumption is gaining interest. In this paper, we explore, for the first time, the relationship between network robustness, performance and Internet power consumption. We first discuss such a relationship based on data collected from Internet sources. Next, we propose a modeling framework to size that relationship. It is...
Throughput and energy efficiency are two important parameters to evaluate the performance of a wireless sensor network (WSN). For WSNs involved in varying channel conditions packet transmission reliability can be affected. This results in increased number of retransmissions and therefore energy consumption, with low throughput. Making optimal choices for robust packet transmission in this scenario...
With the energy reduction become more and more popular, power company need to build AMR system to improve energy efficiency. Many AMR systems around the world have used PLC as communication channel and it's the same in China. BPL technology has become more mature, and it's reliability, stability and practicality has been verified in a number of field trial which shows great potential in the future...
