Applications of sensor networks have become an emerging technology which can monitor a specific area and collect environmental data around the district. The energy of sensor nodes is tightly constrained so that there is a need to control the power consumption in node operations such as transmission and routing. In this paper, we carry out analysis on energy-aware routing in order to minimize th...

Primitive routing protocols for ad-hoc networks are “power hungry” and can therefore consume considerable amount of the limited amount of battery power resident in the nodes. Thus, routing in ad-hoc networks is verymuchenergy-constrained. Continuousdrainage of energydegrades battery performance as well. If a battery is allowed to intermittently remain in an idle state, it recovers some of its l...

We study the problem of integrated topology control and routing in Free Space Optical (FSO) mesh backbone networks. FSO links are high-bandwidth, low interference links that can be set-up very fast, making them suitable for mesh networking. FSO networks are highly constrained by interface constraints, i.e., constraints on the number of FSO links a node can establish. We prove the problem to be ...

Vehicular ad hoc networks (VANETs) can provide ascendable results for dynamic route planning and condition-aware advertisement using short-range wireless interaction. This paper shows routing mechanisms dealing with performance characteristics in their plan, such as big solidity and constrained strength. It can provide good production for a large spectrum of applications. The objective of this ...

This document presents requirements specific to home control and automation applications for Routing Over Low power and Lossy (ROLL) networks. In the near future, many homes will contain high numbers of wireless devices for a wide set of purposes. Examples include actuators (relay, light dimmer, heating valve), sensors (wall switch, water leak, blood pressure), and advanced controllers (radiofr...

Wireless sensor networks consisting of large numbers of inexpensive energy-constrained nodes are an area of emerging networking research. Routing algorithms in these networks are required to provide tolerance to temporary or lasting faults in individual devices. The conventional methodology is to set radio transmit powers to the minimum levels required for connectivity and use multipath routing...

Mobile Adhoc Networks (MANETs) include wireless devices communicating over bandwidth-constrained links with nodes being free to move, join or leave network. Limited range wireless communication and node mobility ensure that nodes cooperate with each other to network and with underlying network, dynamically changing to meet needs continually. This research investigates performance of a highly dy...

Multiobjective formulations are realistic models for many complex engineering optimization problems such as QoS routing protocol for mobile ad hoc network. The paper presents QoS routing protocol for MANET with specialized encoding, initialization, crossovers, mutations, fitness selections and route search using genetic algorithm with multiple objectives. The aim is to find the best QoS route i...

Multi-constrained path (MCP) selection is one of the great challenges that QoS routing (QoSR) faces. To address it in an efficient and highly responsive manner, we propose a new QoSR algorithm, namely NM MCP. Using the Dijkstra’s algorithm with respect to each link metric, NM MCP pre-computes k primary paths, where k is the number of link weights. When a routing request arrives, it executes a m...
