This is the first method that allows analytical study of the Wi-Fi network performance with consideration of correlated channel failures usually inherent to wireless channels. Within the study, we consider the possible packet fragmentation that can be adopted to reduce the performance waste caused by noise-induced distortions. In addition to the throughput, our method allows estimation of the probability of a packet rejection occurring when the number of packet transmission retries attains its limit. The obtained numerical results of investigating Wi-Fi LANs by the developed method are validated by simulation and show high estimation accuracy as well as the method efficiency in determining the optimal fragmentation threshold.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Singhal, Siva Prasad Yarravarapu","doi":"10.1109/MAHSS.2004.1392092","DOIUrl":"https://doi.org/10.1109/MAHSS.2004.1392092","url":null,"abstract":"Ad-hoc on-demand routing protocols like AODV establish and maintain routes on-demand. However, the paths established by on-demand protocols, which are optimal during the route establishment phase, become sub-optimal over time due to node mobility. We propose a path compression algorithm (PCA) that optimizes the established routes when feasible without incurring extra overhead. By utilizing a promiscuous mode of operation, nodes 'hear' hop counts embedded in the IP optional header of data packets to find shorter paths. PCA avoids unnecessary aggressive and ephemeral route updates, which improves the protocol performance. Routing path optimality is important as the optimal path reduces the packet drop ratio, the end-to-end delay, and the energy dissipation of end-to-end data transmission. We conducted simulations using GloMoSim to evaluate the performance of our algorithm and compared it with AODV and a related protocol in the literature - SHORT. Our simulation results show that PCA achieves high delivery rate, low control overhead, low end-to-end delivery and low average hop count compared to both AODV and SHORT.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

The framework eliminates the counting-to-infinity problem found in AODV and other on-demand routing protocols based on destination sequence numbers. The sequence-number window routing (SWR) protocol is presented as an example of this framework. SWR is compared via simulations with DSR, AODV and OLSR using networks of 50 and 100 mobile nodes; the results indicate that SWR is as efficient as AODV without incurring counting to infinity.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Besides, available storage is scarce due to their small physical size. Therefore choosing the most storage- and energy-efficient block cipher for WSN is important. However to our knowledge so far no systematic work has been conducted in this area. We have identified the candidates of block ciphers suitable for WSN based on existing literature and authoritative recommendations. We have benchmarked these candidates and based on this benchmark, we have selected the suitable ciphers for WSN, namely Rijndael for high security and energy efficiency requirements; but MISTY1 for good storage and energy efficiency. In terms of operation mode, we recommend output feedback mode for static networks, but counter mode for dynamic networks.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.
