Research ArticleOpen accessAll words, across the recordUtilization of AODV in Wireless Ad Hoc NetworksZeyad M. Alfawaer, GuiWei Hua, Nidal A. HamdehAODV is a mature and widely accepted routing protocol for Mobile Ad hoc Networks (MANET), it has low processing and memory overhead and low network utilization, and works well even in high mobility situation. We modified AODV to use these dominating sets, resulting in the AODV-DS protocol. Our contribution in addressing the fragility of a minimum connected dominating set in … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,160 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFast Iterative Frequential Equalization, Application to Mobile CommunicationsM. T. Taba, S. Femmam, M. BeddaThe Space Time Adaptive Processing (STAP) is a promising approach in the improvement of the wireless communication systems. Since it makes possible to reduce interferences ISI (Inter Symbol Interference) and CCI (Co-Channel Interference) but its disadvantage is the intensive treatment which reduces the speed of convergence of the algorithm LMS (Least Mean Square) and SMI (Sampling Matrix Inversion). Our approach … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 6,813 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Variable Neighborhood Search Algorithm for Assigning Cells to Switches in Wireless NetworksMatthieu Andr, Gilles Pesant, Samuel PierreThe problem of assigning cells to switches in wireless networks consists of minimizing the total operating cost, that is, the cost of linking cells to switches and the cost of handover from one cell to another, by taking into account factors such as network topology, switch capacity and traffic load in the entire network. Such a problem is well known … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,748 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordDynamic Route Shortening and Route Repairing Mechanism for Mobile Ad Hoc NetworksS. Revathi, T. R. RangaswamyProblem statement: Ad hoc Networks are wireless networks without any fixed infrastructure. The network topology changes frequently and unpredictably due to the random movement of the nodes. The Ad Hoc on Demand Distant Vector Routing (AODV) protocol works in a dynamic fashion, by establishing a route on demand and continues that route until it breaks. Due to the changing network … …Journal of Computer Science, Vol. 8, Issue 8 · 11 Jul 2012 · 7,068 accessesView PDFCite

PurusothamanProblem statement: In sensor networks, some routing protocols performance differs under different mobility models. In ns2, there are two kinds of directed diffusion protocols, rate based gradient mechanism (diffusion/rate) and probability based gradient mechanism (diffusion/prob). In this research, we proposed a method to improve the performance of Directed diffusion/prob protocol by adding a new interest message propagation mechanism and analyzed … …Journal of Computer Science, Vol. 8, Issue 5 · 25 Feb 2012 · 6,749 accessesView PDFCite
