Software Defined Networking (SDN) is an approach developed to facilitate next generation computer networking by decoupling the traffic control system from the underlying traffic transmission system. One key focus in the transition of next-generation computer networking is the service management improvement of network connectivity services. Connectivity across the global digital network requires a...
The defects in traditional Wireless sensor networks (WSN) architectures are firstly studied, and then the typical requirement objectives of WSN are acquired by analysis. Because the WSN is mostly intended for variable and inhospitable environments, where persistent and continuous energy supply is lacking, the environment adaptive and energy efficient capabilities are integrant for WSN architecture...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
