An optimum sensor nodes arrangement in a Wireless Sensor Network (WSN) would be able to provide a WSN with maximum coverage, minimum energy consumption and guaranteed connectivity. A sensor node placement algorithm called Multi-objective Territorial Predator Scent Marking Algorithm (MOTPSMA) that imitates the behavior of territorial predators in marking their territories with their odours is introduced...
An upstream access scheme for Ethernet passive optical networks, called the intelligent fuzzy-logic-based dynamic bandwidth allocation algorithm (IFLDBA) has been proposed. The algorithm provides the allotment of bandwidth between optical network units (ONUs) and within ONUs. Fuzzy logic is used to improve the bandwidth allocation within each ONU. We compare the IFLDBA algorithm with the existing...
Passive optical networks (PONs) are thought to be the next step in the development of access networks and providing broadband access in the ??last mile?? area. Ethernet PON (EPON) gains the most attention from the researchers as it offers highly flexible and cost effective solution. In this paper we propose two high level scheduler algorithms inside the optical line terminal (OLT) and optical network...
In this paper, an efficient dynamic bandwidth allocation (DBA) algorithm based fuzzy logic for upstream Ethernet passive optical networks (EPON) is proposed. The algorithm provides the allotment of bandwidth for inter optical network unit (ONU) and intra ONU. We compared the performance of DBA algorithm based fuzzy logic and DBA algorithm without fuzzy logic in terms of bandwidth utilization and delay...
We proposed a fuzzy-logic-based dynamic bandwidth allocation (FLDBA) algorithm for upstream Ethernet passive optical network (EPON). In the proposed DBA algorithm, the optical line terminal allocates bandwidth to the optical network units in proportion to the priority category of the traffic class. Simulations were performed to prove the accuracy of the FLDBA algorithm by comparing the algorithm with...
