In this paper, we describe our participation in the interactive and adhoc tracks of CHiC 2013.

1 Enhancing security features & performance of AODV protocol under attack for MANET In this paper, a novel security mechanism is presented to enhance security & performance of AODV (Adhoc On-demand Distance Vector) routing protocol under the attack for MANET (Mobile Ad-hoc Networks). The AODV routing protocol was initially developed without considering security in mind. So it is not able to def...

سابقه و هدف: جنگل­ های زاگرس به ­عنوان یکی از بوم ­سازگان­ جنگلی مهم ایران پوشش­ گیاهی (درختان، درختچه ­ها گونه­ علفی) متنوعی برخوردار می­ باشد. شناسایی آگاهی دقیق نقش ­شناختی آنها در این ­سازگان تواند حفاظت منابع طبیعی توسعه پایدار کمک شایانی نماید. به‌منظور مطالعه تنوع گونه‌ای گیاهان چوبی ذخیره کربن خاک رابطه با عوامل فیزیوگرافیک (جهت، شیب ارتفاع سطح دریا)، رویشگاه کیکم (var. cinerascens Acer...

This paper investigates the issue of connectivity of a wireless adhoc network in the presence of channel impairments. We derive analytical expressions for the node isolation probability in an adhoc network in the presence of Nakagami-m fading with superimposed lognormal shadowing. The node isolation probability is the probability that a randomly chosen node is not able to communicate with none ...

We report on the participation of the CSIRO team in the TREC 2012 Microblog Track. We participated with four automatic runs for the adhoc search task and four automatic runs for the filtering task. In the adhoc search task, we experiment with different pre-processing and query expansion techniques. Our most important finding is highlighting the value of systematic pre-processing of tweets and i...

The current growth of speedy voice transmission over Mobile Adhoc wireless networks has enabled the deliverance of multimedia broadcasting services to mobile users. They play a vital role in business environments where permanent access to network resources act as key factor. . This document is a survey of the voice communication in wireless networks. The various issues related to implementation...

There are various TCP variants and each one belongs to a different criteria. In this paper we discuss about the congestion problem in Adhoc networks and compare the performance of three TCP variants that all work on different techniques. This paper compares TCP variants specifically TCP Tahoe, Reno and Lite based on different parameters such as number of nodes received with error, packet loss, ...

We introduce an ultra-low complexity decentralized control scheme for adhoc mobile sensor networks that can be used for a great variety of sensing tasks. Sensor networks using this control scheme are easy to configure, can operate completely autonomously without supervision, and automatically adapt to various environmental changes. Moreover, they are robust to individual sensor failure as well ...

In this project, we investigate the performance of routing protocols employed for data transmission using real life protocols like “TCP/IP” in wireless adhoc networks. We come up with simple metrics to measure the efficiency of routing protocols. We study the behavior of TCP on multiple wireless hops and suggest design guidelines for increasing the “overall efficiency” of a routing protocol. We...
