“…El tamaño de los paquetes a enviar tiene una gran relevancia a la hora de implementar una red, debido a que al aumentar la cantidad que se envía, crece el Throughput, el cual es el nú-mero de paquetes recibidos por el nodo de destino, pero se debe tener presente que el PDR (relación entre los paquetes que llegan satisfactoriamente a su destino con el número total de paquetes transmitidos) aumenta hasta cierto punto a medida que se aumenta la cantidad de paquetes, pero llega un punto en el cual si se sigue incrementando esta cantidad, el PDR comienza a descender [10].…”

RESUMENEn este artículo se realiza un estudio del efecto de la movilidad de nodos y subredes así como del tamaño de los paquetes sobre el protocolo de capa MAC, IEEE 802.11 utilizado por OPNET para las redes móviles Ad-Hoc. A partir de los resultados de las simulaciones de diferentes escenarios se obtiene un modelo matemático que permite predecir las pérdidas en una topología con subredes mó-viles para así reducir el tiempo de diseño e implementación de las mismas. Para ello se estudian los resultados de pérdidas de datos obtenidos en una topología con dos subredes móviles y se obtiene un modelo matemático que determina las pérdidas para el protocolo de enrutamiento utilizado. ABSTRACTThis paper presents a detailed study about the effects of node (and sub-network) mobility, as well as packet size, on MAC protocol IEEE 802.11 (as used by OPNET for Ad-Hoc networks). A mathematical model is obtained based on simulation results representing different network scenarios. The model allows predicting packet losses over a mobile-sub-network topology so as to reduce the design and implementation time span. Data-loss-associated results are analyzed over a mobile two-sub-network topology, yielding the mathematical model that serves to estimate packet losses for a particular routing protocol.

“…The aim of this paper is to evaluate the Performance of Handover in WiMax with TCP and UDP protocols. Performance matrices in term end-to-end delay and throughput, which is defined as the average rate of successful message delivery over a communication channel (Zahian and Hassan, 2011a;2011b), were used in this study against packet size and traffic load. This paper contains six main sections.…”

The rejection of an ongoing connection/session is serious problem and it degrades the QoS and efficiency of the network rather than rejecting a request for new connection. The impact on performance of handovers is a serious problem in cellular systems that must be addressed. During handover there may be delay in packets and connections may drop. Real time applications i.e., VoIP and streaming video can be adversely affected by such kind of delays. In this study we used TCP and UDP as an underlying protocol for exchange of data between two wireless mobile nodes in a WiMax access network and had evaluated the effect on performance in terms of end-to-end delay and throughput. The results showed that when handover is triggered the transfer window resets to zero causing higher throughput and end-to-end delay for TCP than UDP based on packet size and traffic load.

Jamming attack is main problem and this can affect the network by various ways. Sometimes jammer retransmits messages to create jam over network or sometimes jammers are radio jammer which disturbs communication by decreasing the signal to noise ratio. In previous researches various techniques are discussed to detect jamming. One way is to check the signal busy ratio. If channel is busy for long time that means there is a jam on network or it can be check by checking the threshold value. If threshold value exceeds up to some limit then there expect some jam on network. When the jam will detected then check will be performed on the node which will be creating jam. Node identity will be checked by calculating the distance and the message of that node will be checked to detect the retransmission and replays. If sequence number will same than attacker will be detected but if sequence number is different message content will be checked. To check the reason of retransmissions an additional message will be send to destination so that if re-transmissions are due to the network failure it can be detected.
