In this paper the performance analysis of a routing algorithm for MANETs called Service Zone Gateway Prediction (SZGP) is presented. This is a non-cooperative and hybrid type of routing with a hierarchical multilayered structure, incorporating pre-computed multipath hop-by-hop distributed connectivity. The goal is balance of the load among the nodes and reliable and energy efficient communication...
Data center energy consumption has become one of the top concerns in designing and operating large-scale data centers as cloud service providers such as Amazon, Google, IBM and Microsoft have begun to establish more data centers in response to growing requests in clouds. In recent years, extensive efforts have been put into the research of reducing the energy consumption of servers. With the improvement...
In this paper, we propose an energy efficient multipath congestion control protocol, called emReno. emRemo can shift traffic to the lower energy cost path without sacrificing the throughput and still guaranteeing the fairness and load balancing. The extensively simulations show the features of emReno as a common multipath congestion control protocol as well as its energy efficient characteristic.
In this paper, a high-flexibility and energy-efficient reconfigurable symmetric cryptographic processor architecture is presented, which is based on very-long instruction word (VLIW) structure. By analyzing basic operations and storage characteristics of symmetric ciphers, the application-specific instruction-set system for symmetric ciphers is proposed. Eleven kinds of reconfigurable cryptographic...
A wireless sensor network (WSN) has its application in various fields such as temperature monitoring, pressure monitoring, health monitoring, defence system etc. In wireless sensor networks, congestion occurs because of the inadequate resources like low processing power of the sensor node. The performance of the WSN is degraded by the congestion as it leads to the wastage of energy, reduction in throughput...
This paper introduces a new contention window (CW) adaptation algorithm with the main objective of reducing energy consumption while maintaining required Quality of Service (QoS) for multi-class traffic with different priorities. The main concept of the proposed algorithm is adaptively adjust the contention window (CW) size according to the network load conditions and each traffic class applies different...
Health monitoring system has been an important application in the last decade. There are many types of health sensors that make this system worth and real like wearable sensor, bed sensor and ECG sensor. Primarily, these sensors operate on the license-free 2.4-GHz industrial, scientific, and medical band (ISM). This feature makes this system not only easily applicable, but also probably vulnerable...
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...
Nowadays the rapid growth of user data rate requirement prompts dense deployment of small cell.

Mobile data offloading has been proposed as a solution for network congestion. However, the majority of the state-of-the-art is focused on the downlink offloading, while the change of mobile user habits, like mobile content creation and uploading, makes uplink offloading a rising issue. In this work we focus on the uplink offloading using Ip Flow Mobility (IFOM). IFOM allows a LTE mobile User Equipment...
