This new generation of networks is different from the earlier one in many aspects like network infrastructure, resources and routing protocols, routing devices etc. These networks are bandwidth and resource constrained with no network infrastructure and dedicated routing devices. Moreover, every node in such networks has to take care of its routing module itself. These characteristics become reasons for the importance of security in mobile ad-hoc networks as there is very high probability of attacks in such networks. Some work has been done to compare different protocols on basis of security but keeping in view the resource limitations in such networks, evaluation based on networking context is also important. We evaluate the overall performance overhead associated with secure routing protocols for mobile ad-hoc networks (MANETs). We implement the secure ad-hoc on-demand distance vector routing protocol (SAODV) extensions with AODV in the network simulator 2 (NS-2) and use the Monarch project implementation of Ariadne for our evaluation purpose. We try to figure out the amount of extra work a mobile node has to do in order to operate securely","PeriodicalId":58925,"journal":{"name":"Digital Communications and Networks","volume":"27 1","pages":"971-975"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73449031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attempted packet transmissions are modeled as a three dimensional Poisson point process in space and time. Each node measures the total interference power before an attempted transmission, and proceeds with the transmission only if the total interference power is below a threshold, called the idle threshold. A completed transmission is successfully received if the interference power at the intended destination is suitably low during the transmission. The total interference process is modeled as a shot noise that is a filtered in space and time, which accounts for an infinite number of concurrent transmissions on the infinite plane. We make a Gaussian approximation for the power of the interference process. A key mechanism for physical carrier sensing we take into account in our model is the inhibitory effect of nearby neighbors around an existing transmission. The inhibiting model is based on the threshold on the interference level rather than a geographically defined region. We model this effect using the conditional intensity of transmissions given an existing transmission, which can be solved using a system of two fixed point equations. We further approximate the conditional statistics of transmissions as Poisson to obtain a simpler model. We compare the predictions using the simpler model to Monte Carlo simulations results based on the model without the Poisson approximation, and we find a reasonably close match. Our results suggest the simpler model can be used as a guide to set the protocol parameters such as transmission attempts intensity, distance between the transmitter and its intended receiver, transmission power, packet duration, idle and packet detection threshold, in order to optimize network throughput","PeriodicalId":58925,"journal":{"name":"Digital Communications and Networks","volume":"16 1","pages":"276-285"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73730396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the resource constraints in wireless environment may render difficulty to realizing all the desirable services. Consequently, an infrastructure with high data rate is necessary to complement the resource constraints and to act as anchor points linking mobile nodes to other fixed networks as the Internet. Hybrid wireless networks have emerged as a promising solution, allowing mobile clients to achieve higher performance and service access in a seamless manner independent of their existence in wireless LAN (WLAN) communication range. In this paper we address the benefits of hybrid wireless networks, showing their possible applications and presenting a classification for their emerging architectures. Also, we identify the research challenge arising from the problem of applying the grid computing concept in such hybrid wireless environment, showing the expected benefits from the aggregated fixed-mobile capacity. Finally, we propose our vision for a potential architectural model, which is expected to provide useful services by the network operator or the service provider in such a hybrid environment","PeriodicalId":58925,"journal":{"name":"Digital Communications and Networks","volume":"54 1","pages":"848-853"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80056010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
