Achieving both energy efficiency and scalability at the same time is a challenging task in wireless sensor networks (WSN). In this paper, we describe the mechanism of Cluster Based Anycast Routing protocol (CBAR) for routing in WSN. This is very crucial to ensure that the system operates at minimum energy with increasing scalability and network life-time in WSN. Main objective of this research ...

The Internet’s current numbering system is nearing exhaustion: Existing protocols allow only a finite set of computer numbers (“IP addresses”), and central authorities will soon deplete their supply. I evaluate a series of possible responses to this shortage: Sharing addresses impedes new Internet applications and does not seem to be scalable. A new numbering system (“IPv6”) offers greater capa...

ireless sensor networks are composed of large number of tiny sensor nodes that are used to observe, monitor and collect data about a certain phenomenon of interest. Wireless sensor networks are often deployed randomly due to the harsh environments and their hard to reach locations. The sensor nodes used in wireless sensor networks are energy constrained. Energy efficiency is thus the main conce...

The integration of multicore processors into wireless mobile devices is creating new opportunities to enhance the speed and scalability of message routing in ad hoc networks. In this paper we study the impact of multicore technology on routing speed and node efficiency, and draw conclusions regarding the measures that should be taken to conserve energy and prolong the lifetime of a network. We ...

The logic blocks of most modern FPGAs contain clusters of look-up tables and flip flops, yet little is known about good choices for several key architectural parameters related to these clusters. There are three basic questions: how many look-up tables should a cluster contain, how should the flexibility of FPGA routing change as the cluster size changes, and how many inputs should the programm...

With the increasing demand for real time applications in the Wireless Senor Network (WSN), real time critical events anticipate an efficient quality-of-service (QoS) based routing for data delivery from the network infrastructure. Designing such QoS based routing protocol to meet the reliability and delay guarantee of critical events while preserving the energy efficiency is a challenging task....

A critical need in Mobile Wireless Sensor Network (MWSN) is to achieve energy efficiency during routing as the sensor nodes have scarce energy resource. The nodes’ mobility in MWSN poses a challenge to design an energy efficient routing protocol. Clustering helps to achieve energy efficiency by reducing the organization complexity overhead of the network which is proportional to the number of n...

This study formulates a two-objective model by individually minimizing shipping costs and inventory costs to decide whether to route a shipment through a hub or directly to its destination. First, shipping and inventory cost functions are formulated for a multi-port calling route. Shipping costs include capital and operating cost, fuel cost and port charge, while inventory costs include waiting...

Due to the limited lifetime of the nodes in ad hoc and sensor networks, energy efficiency needs to be an important design consideration in any routing algorithm. It is known that by employing a virtual backbone in a wireless network, the efficiency of any routing scheme for the network can be improved. One common design for routing protocols in mobile ad hoc networks is to use positioning infor...
