Routing protocols for multi-hop wireless networks have traditionally focused on finding the best path for forwarding packets between a pair of nodes. While such single-path forwarding is suitable for wired networks with relatively stable point-topoint links, it is not an ideal approach for wireless networks with broadcast links of time varying qualities. Opportunistic routing schemes, which exp...

Recently, we had proposed a novel network density and mobility aware energy-efficient broadcast route discovery strategy (called DMEF) to discover stable routes in mobile ad hoc networks (MANETs). DMEF works by letting each node to dynamically choose its own broadcast transmission range for the route discovery messages depending on the perceived number of neighbour nodes in its default maximum ...

The dynamic broadcast problem is the communication problem where source packets to be broadcast to all the other nodes are generated at each node of a parallel computer according to a certain random process, such as a Poisson process. The lower bounds on the average reception delay required by any oblivious dynamic broadcast algorithm in a d-dimensional hypercube are Ω(d + 1 1 ρ) when packets a...

Architectures built using bottom-up self-assembly of nanoelectronic devices will need to tolerate defect rates that are orders of magnitude higher than those found in current CMOS technologies. In this paper, we describe and evaluate an approach to provide defect isolation in such an architecture that consists of a large number of simple computational nodes, each of which can communicate with f...

Routing method is a key technology for swarm communication. In order to reduce the node energy consumption in large-scale communication, routing based on moth search link distance and residual proposed. First, network divided into sub-cluster networks by filtering of cluster head nodes. The with more used as forward data signals from other between edge nodes established relaying function calcul...

Protocols play a role in network connectivity and performance. The techniques for routing packets across a network vary among protocols. In this paper, a brief review of six protocols which are employed by Cisco systems were made and they are Open Shortest Path First(OSPF), Enhanced version of Interior Gateway Protoco(EIGRP)l, Routing Information Protocol(RIP), Open System Interconnection(OSI),...

Mobile Adhoc Networks (MANET) is decentralized, self configuring, wireless network of mobile devices without using any infrastructure. MANET required dynamic routing to respond to the topological changes as nodes are dynamic in nature. Dynamic routing protocol such as Adhoc on demand distance vector routing (AODV) with Expanding Ring Search (ERS) is widely used technique to reduce energy consum...

The use of wireless sensor networks in home automation (WSNHA) is attractive due to their characteristics of self-organization, high sensing fidelity, low cost, and potential for rapid deployment. Although the AODVjr routing algorithm in IEEE 802.15.4/ZigBee and other routing algorithms have been designed for wireless sensor networks, not all are suitable for WSNHA. In this paper, we propose a ...

We have designed a scalable and expressive naming system called SENS, capable of retrieving information of computing and content resources distributed widely across the Internet through exact queries and multi-attribute range queries over resource names. Our system utilizes a descriptive naming scheme to name resources and a multi-dimensional resource ID space for message routing through an ove...
