Research ArticleOpen accessIn the abstractDensity Based Routing Algorithm for Spare/Dense Topologies in Wireless Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: A Mobile Ad-Hoc Networks (MANETs) operate in environments without infrastructures with an undefined network size. Most routing protocols of Mobile Ad-hoc Networks (MANETs) were studied using open space models where nodes were able to move throughput the entire simulation area. However, a more realistic topology should account for restricted mobility of nodes, such as in an urban city … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,465 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Mobile Agent Information Retrieval SystemR. Punithavathi, K. DuraiswamyProblem statement: Most of the information retrieval systems used only client-server architectures. The client-server model though powerful, had some limitations. In mobile computing environment which has both wired network and wireless networks with limited communication capabilities, the performance of the system was very low. Approach: Mobile agents are considered a suitable technology to develop applications such as information retrieval system … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Efficient Hidden Markov Model Based Target Tracking Mechanism in Wireless Sensor NetworksB. Amutha, M. PonnavaikkoProblem statement: Target tracking is a challenging application in Wireless Sensor Networks (WSNs) because it is computation-intensive and requires real-time location processing. This study proposes a practical target tracking system based on the Hidden Markov Model in a distributed signal processing framework. In this framework, wireless sensor nodes perform target detection and tracking, whereas target localization requires the collaborative signal … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Stable Weight-Based on Demand Routing Protocol for Mobile Ad Hoc NetworkOon Chong Hsi, Azizol AbdullahProblem statement: A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. Approach: A Stable Weight-based On demand Routing Protocol (SWORP) that uses the weight-based route strategy to select a stable route was created by Wang. But SWORP … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,933 accessesView PDFCite
Research ArticleOpen accessIn the abstractReducing Broadcast Overhead Using Clustering Based Broadcast Mechanism in Mobile Ad Hoc NetworkN. Karthikeyan, V. Palanisamy, K. DuraiswamyProblem statement: Network wide broadcasting is an important function in Mobile Ad Hoc Networks (MANET), which attempts to deliver packets from a source node to all other nodes in the network. Broadcasting is often very useful for route discovery, naming, addressing and helping multicast operations in all kinds of networks. For designing broadcast protocols for ad hoc networks, one of … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Light-Weight Service Discovery Protocol for Ad Hoc NetworksRanwa Al Mallah, Alejandro QuinteroProblem statement: In mobile ad hoc networks devices do not rely on a fixed infrastructure and thus have to be self-organizing. This gives rise to various challenges to network applications. Existing service discovery protocols fall short of accommodating the complexities of the ad-hoc environment. However, the performance of distributed service discovery architectures that rely on a virtual backbone for locating … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncremental DataGrid Mining Algorithm for Mobility Prediction of Mobile UsersU. Sakthi, R.S. BhuvaneswaranProblem statement: Mobility prediction is the important issue in Personal Communication Systems (PCS). Mobile users moving logs are stored in data grid located in different locations. Distributed data mining algorithm is applied on this moving logs to generate the mobility pattern of mobile users. As new moving logs are added to the data grid, existing mobility pattern becomes invalid and … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 6,776 accessesView PDFCite
Research ArticleOpen accessIn the abstractVirtual Mobility to Improve Cooperation in Mobile Ad hoc NetworksA. Baaziz, S. PierreWe study the impact of mobility on the level of cooperation between mobile nodes in a mobile ad hoc network. In a mobile ad hoc network, if the nodes are static or have a reduced mobility and if some nodes adopt a selfish behaviour, the performance of the network is affected. This is because the same nodes that are relaying … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocal Beam Search Algorithm for Power Saving in Clustered Ad-Hoc NetworksA. Zabian, F. Al-KalaniAn ad-Hoc network is an infrastructures network consisting of mobile moving nodes. Every node in network performs as a router or a package forwarder. Energy consumption of network interfaces can be significant. There is a relationship between the transmission power and the distance traveled by a packet, increasing the transmission power increases the reachable area at the cost of high … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,544 accessesView PDFCite
