The fire localization using a distributed consensus finding algorithm in a wireless sensor network is described. The fire is circumscribed by a circle. The information is available at all sensor nodes that are alive, which makes it robust against failures and losses. Minimizing energy consumption is crucial for sensor nodes that have to function autonomously as long as possible. Therefore, the ...

To characterize the behavior of a mobile ad-hoc network (MANET), the Brownian mobility model is studied, where the random coordinators of mobile nodes are modeled by the Brownian motion. Based on the Brownian mobility model, the average relative speed of mobile nodes in a MANET cluster and the expected value as well as the variance of link lifetime are derived for node pairs. The expected link ...

In this paper we explore a symmetry-based search space reduction technique which can speed up optimal pathfinding on undirected uniform-cost grid maps by up to 38 times. Our technique decomposes grid maps into a set of empty rectangles, removing from each rectangle all interior nodes and possibly some from along the perimeter. We then add a series of macro-edges between selected pairs of remain...

We explore a symmetry-based reformulation technique which can speed up optimal pathfinding on undirected uniform-cost grid maps by over 30 times. Our offline approach decomposes grid maps into a set of empty rectangles, removing from each all interior nodes and possibly some from along the perimeter. We then add macro-edges between selected pairs of remaining perimeter nodes to facilitate prova...

For the energy and computing capability of nodes are limited in Wireless sensor networks (WSNs). In order to decrease the dead speed of the nodes, proposes an uneven clustering routing protocol for wireless sensor networks based on Fruit Fly Optimization Algorithm (FOA-UCR). By using Fruit Fly Optimization Algorithm to select a set of optimal nodes as cluster heads and selects secondary nodes f...

we report a case of a 68-year-old female who was a known case of diabetes mellitus and chronic liver disease and presented with complaints of dry cough and other constitutional symptoms since one month. during initial investigations, the patient was found to have peripheral blood eosinophilia. upon investigating further,the patient was found to have mediastinal lymphadenopathy and fine-needle a...

breast cancer is one of the most common malignancies in the world. the most important prognostic factor in this cancer is the stage of the tumor. detection of lymph nodes with or without malignancy is essential for determining the stage of the tumor and setting a therapeutic plan. there are different methods for isolating lymph nodes in surgical specimens of breast cancer in the pathology depar...

in this paper, an efficient fault-tolerant routing algorithm for mobile ad-hoc networks (manets) is presented. the proposed algorithm increases the network fault-tolerance using natural redundancy of ad-hoc networks. this algorithm is carried out in two stages; 1) the selection of backup nodes 2) the selection of backup route(s). in the first stage, the proposed algorithm chooses nodes with the...

Body area networks is one of the types of wireless area networks which has been created to optimize utilizing hospital resources and for earlier diagnosis of medical symptoms, and ultimately to reduce the cost of medical care. This network like most of the wireless networks is without infrastructure and the embedded sensor nodes in the body have limited energy. Hence, the early power completion...
