Mobile adhoc network (MANET) is a collection of mobile devices which form a communication network with no preexisting wiring or infrastructure. Multiple routing protocols have been developed for MANETs. As MANETs gain popularity, their need to support real time applications is growing as well. Such applications have stringent quality of service (QoS) requirements such as throughput, end-to-end ...

In the design of protocols and algorithms energy awareness for computation and protocol management is becoming a crucial factor. On the other hand, to support node mobility many scalable routing strategies have been designed. These protocols try to consider the path duration with respect to some QoS constraints and to reduce the route discovery procedures. In this paper, a novel routing strateg...

In this paper, we compare the Dynamic Source Routing (DSR) protocol and our Energy Aware Dynamic Source Routing protocol (EADSR). The implementation of the routing protocols is carried out using the Click modular router infrastructure on laptops with wireless ethernet cards running Linux. We demonstrate the working of both ad hoc routing protocols through our experiments and highlight the energ...

The energy efficiency and quality of service (QoS) provisioning of wireless multimedia sensor networks (WMSNs) are two major issues that impact the application of such networks. Recent studies demonstrate that network performance can be greatly improved by involving multiple sinks. However, mainstream WMSN routing protocols are generally designed to account for a single sink. This paper propose...

Biomedical wireless sensor networks are a key technology to enable the development of new healthcare services and/or applications, reducing costs and improving the citizen’s quality of life. However, since they deal with health data, such networks should implement mechanisms to enforce high levels of quality of service. In most cases, the sensor nodes that form such networks are small and batte...

Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...

There are many challenges when designing and deploying wireless sensor networks (WSNs). One of the key challenges is how to make full use of the limited energy to prolong the lifetime of the network, because energy is a valuable resource in WSNs. The status of energy consumption should be continuously monitored after network deployment. In this paper, we propose coverage and connectivity aware ...

Nodes in Mobile Ad Hoc Networks (MANETs) are limited battery powered. That‟s why energy efficient routing has become an important optimization criterion in MANETs. The conventional routing protocols do not consider energy of the nodes while selecting routes which leads to early exhaustion of nodes and partitioning of the network. This paper attempts to provide an energy aware routing algorithm....

Typical communication patterns within a sensor network are data delivery from sensor nodes to one of selected information sinks, and information sinks requesting a certain physical phenomenon or requesting sensor nodes lying within a sensed area. In general, addressing is achieved by utilizing sensor locations. Geographic routing algorithms allow routers to be nearly stateless since packet forw...
