Today, Wireless Sensor network are used in many applications to gather sensitive information which is then forwarded to an analysis centre. This paper proposes a new routing method for WSNs to extend network lifetime using combination of fuzzy approach and an A-star algorithm. The proposed method is to determine an optimal routing path from the source to the destination by favoring the highest ...

Many real-time applications use Internet as a media to transmit their data and need guarantee for correct data transmission and limited transmission delay. It requires efficient network traffic protocols to avoid or limit the level of congestion. In this paper we propose, design and analyze a Robust Delay Based Controller (RDBC) for traffic management on transmission control protocol (TCP). Thi...

This report is my final report for ICS/EECS 243E course project. My project topic is – Mobile Ad-hoc Networks (MANET) Routing Protocols Simulation and Comparison. Reseaches and challenges on MANET will be briefly discussed in this report. A group of mobile ad-hoc networks (MANET) routing protocols – Dynamic Source Routing (DSR), Ad-Hoc On-Demand Distance Vector Routing (AODV), and Destination-S...

Adhoc on demand distance vector routing protocol(AODV) is specially designed for mobile adhoc networks with reduced overhead using Expanding Ring Search technique. But energy consumption should also be considered in MANET due to battery constrain of the nodes. In this paper, we choose an energy efficient route discovery process for AODV based on Expanding Ring Search(ERS). We want to saves ener...

Cluster-based routing protocols are one of the most favorable approaches for energy management in wireless sensor networks. The selection of the best cluster heads (CHs), as well as the formation of optimal clusters, is an NP-hard problem. The present study proposes an optimal solution for CHs selection to generate a network topology with optimized network performance. The problem is formulated...

This paper considers performance of mobile ad hoc network (MANET) routing protocols with respect to group and entity mobility models. The three widely used routing protocols have been investigated and compared: Destination Sequenced Distance Vector (DSDV), Ad-hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR). Mobility models encompass: Reference Point Group Mobility (RPGM), ...

This paper aims to compare performance of some routing protocols for Mobile Ad-Hoc networks (MANETs). A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. Data transmission between two nodes in MANETs requires multiple hops as nodes transmission range is lim...

One of the most important aspects a effecting the overall QoS performance of hybrid mobile ad hoc networks is the efficient discovery of Internet gateways. So many previous papers addressed the problem of interconnecting Mobile Ad Hoc Networks (MANET) to the Internet, via one or more attachment points called gateways. The protocol employed to discover available gateways and set up routes to the...

Wireless communication is very extensively used in the current world and we are rapidly moving to a hands-free swift world. Even with the arrival of advancements at such a rate in the wireless world, The Wireless Mesh Networks generally uses the AODV routing protocols to handle the traffic flow in the Mesh network. But our proposed routing protocol can securely discover the route between the pa...

A large number of small tiny device called sensor nodes are use to develop wireless sensor network that can be effectively used as a tool for monitor physical or environmental conditions, such as temperature, sound, vibration, pressure and motion at different locations. There are two major issues, one is energy-efficient routing protocol and other is overall lifetime of the sensor network. This...
