In this paper our work investigates the performance of Intra-WBSN by placing the Body Node Coordinators (BNCs) at different positions in Intra-WBSN. Physiological data is collected by bio-sensor nodes and forwarded to BNC through intermediate node or forwarder. The forwarder node is selected on the basis of cost-function. Cost-function depends on the residual energy of node and path-loss between sensor...
In this era of cloud computing, web services based solutions are gaining popularity. The applications running on distributed environment seek new parameters for them to perform efficiently to satisfy end user's requirements. Finding these parameters for increasing efficiency has become a talk of researchers now days. Non functional performance of a web service is described through User dependent QoS...
Due to rapid growth of Internet and demands for multiple access the request for services have also increased significantly. As a result there is congestion in the network where buffer management plays an important role. Traditionally, Droptail was used as buffer management techniques along with TCP. Due to large queuing delay and TCP synchronization problem of Drop tail, Active Queue Management (AQM)...
This is an era of Internet computing and computing as a service on the internet is called cloud computing. Mainly three services like SaaS (applications), PaaS, and IaaS are being accessed through internet on demand, pay as per usage basis. Quality of Service (QoS) is the main issue in internet based computing for service providers and user-dependent as well as user-independent QoS parameters. In...
In recent development, the use of Wireless Sensor Network (WSN) to handle more complex functions is increasing drastically which in turns requires their powered battery sensors to efficiently utilise their energy in order to prolong the network lifetime for the heterogeneous nodes. Clustering is one of the techniques used to optimise this energy consumption and increasing the network lifetime as well...
Mobile ad hoc network is a collection of mobile nodes which are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. This paper examined routing protocols by varying CBR traffic but having identical...
Several localization techniques have been proposed to identify the exact location of sensor nodes. Localization is important for computation of many applications such as routing in wireless sensor network. Energy preservation is a challenge in wireless sensor network and many algorithms have already been proposed. The localized node lifetime is maximized by using energy-efficient routing, use of minimum...
Future of IP addressing is totally dependent on IPv6 rather than IPv4 to assure the Quality of Service (QoS) requirements and IPv6 have noteworthy advantages over present IPv4. Presently, the conversion mechanisms in Dual Stack Transition Mechanism (DSTM) is taking bit more time, which hampers the overall performance of the network. In this paper we have reduced the time delay of data packets transmission...
An ad-hoc network is a self-sufficient collection of mobile nodes that occur to exist within a close nearness in an interval of time. In this paper, a new optimal energy conserving reverse reactive routing protocol has been proposed that computes the shortest path in between any source-destination pair on demand. The approach, unlike other energy conserving reactive protocols, finds loop-free, increases...
In this paper, we analysis and simulate the AODV and OLSR routing protocols for both Wireless Ad-hoc Network and Wireless Mesh Network. An Ad-hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Wireless Mesh Networks (WMNs) have recently gained a lot of popularity due to their...
