Mobile sink brings new challenges to densely deployed and large wireless sensor networks (WSNs). When the sink moves, frequent location updates from the sink can generate excessive power consumption of sensors. In this paper, we propose IAR, an Intelligent Agent-based Routing protocol that provides efficient data delivery to mobile sink. Proposed algorithm reduces signal overhead and improve degraded...
In this paper, we present a discussion of some architectural principles pertaining to mapping distribution protocols that are common components of proposed designs to improve the scalability of future Internet routing tables. The efficiency of a mapping distribution protocol in terms of response time and the volume of traffic load it generates are important considerations. We consider how Egress Tunnel...
Analysis on the basis of the protocol Gnutella0.6, the use P4P technologies for sensing conveniently network topology information, proposes a P4P-based Gnutella routing algorithm, in which nodes join algorithm to consider the network topology and as far as possible to join super-nodes that close to itself. When routing algorithm forwards query packet, it give priority to select the physical proximity...
Ever since the inception of Internet, scalability has been a major concern to the Internet world. As many Internet Protocol addresses are allocated/assigned, there is rapid increase in the routing table. In view of ameliorating this pitfall, there is need for proper aggregation. Aggregation is the key solution to solving the increase of allocated addresses in the routing table, but the major problem...
Internet routing system is the fundamental components of Internet. As the Internet growth, Internet routing system is facing the scaling issues of global routing table expanding due to the wide use of multi-homing, traffic engineering, and mobility. Existing proposed solutions need to change host protocol stack or routing architecture, hence, no incentive for practical deployment. In this paper, we...
Sensor networks consist of small motes attached with sensors to measure ambient parameters like temperature, humidity and light. As these motes are unreliable due to wireless link quality and also the data measuring sensors cannot be calibrated accurately for a given applications need. The unique data fusion needs are that parameter being measured is distributed across the network and needs to be...
The network in case of Mobile Adhoc networks is generally poorly defined or not defined at all. In Such a network the data can be relayed/routed by intermediate nodes whose position keeps on changing. Mobile adhoc networks have some challenges like Limited wireless transmission range, broadcast nature of the wireless medium, hidden terminal and exposed terminal problems, packet losses due to transmission...
Hierarchical or cluster based routing methods are well-known techniques with special advantages related to scalability and efficient communication. Clustering technique is also utilized as an energy-efficient routing in Wireless Sensor Networks where the nodes with the highest residual energy can be used to gather data and send the information. In this paper, we proposed and analyzed a cluster based...

In contrast to the classical approach of wireless sensor networks, this paper focuses on the development of enhanced network services like multimedia transmissions in a gas concentration monitoring scenario. Therefore,...

Multicast is a one-to-many communication scheme and has largely been studied in such networks. Indeed, this communication primitive can be used as a building block for popular services, such as data streaming or group communication. The particularity of 6Shot is the location-...

We propose a novel congestion-aware routing protocol, which leverages local and remote congestion information for routing decisions. Path congestion is difficult to measure, therefore congestion aware protocols consider only local status. This protocol uses an innovative representation of congestion for router-router links. These congestion statistics are then distributed via an aggregation protocol...
Over the past years, location-based routing protocols have been studied extensively in mobile ad hoc networks (MANETs). However, how to efficiently provide the location information for nodes is still a challenge. So far, many protocols have been proposed to solve this problem, most of which offer exact routing location information, and are complicated to implement in practice. In this paper, we propose...
Recently in order to improve the longevity and energy efficiency of WSN (Wireless Sensor Network), widely research have been carried on. Up to the present, many presented methods are based on clustering hierarchical structure. Nevertheless, these protocols don't consider the problem of data sensibility. Based on cluster hierarchical structure, we propose a routing protocol through which each node...
Wireless Sensor Network (WSN) is one of the major research areas in computer network field today. Data dissemination is an important task performed by wireless sensor networks.

OLSR is a well-known proactive protocol for wireless networks. Although very efficient by many points, it suffers from the drawbacks of not taking into account QoS metrics such as delay or bandwidth.
