We report on the development of an acetylene-filled photonic microcell based assembly process that is contaminant free and requires no helium buffer gas nor gluing procedure. The consists a 7-m-long 30 µm core-diameter inhibited-coupling guiding hollow-core crystal fiber filled with acetylene at pressure in range 80 µbar, sealed by capping its ends fusion-collapsing glass-tube sleeve, mounted F...

in this paper we consider the non-preemptive variant of a multi-mode resource constrained project scheduling problem (mrcpsp) with mode identity, in which a set of project activities is partitioned into disjoint subsets while all activities forming one subset have to be processed in the same mode. we present a depth-first branch and bound algorithm for the resource constrained project schedulin...

Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central management. Moreover, every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at uncertain times. In this paper proposed a Path Establishment & Maintenance Algorithm (PE&MA) that optimizes the established routes ...

Wireless Sensor Networks (WSNs) facilitate, monitoring and controlling of physical environments from remote locations with better accuracy. Sensor networks are dense wireless networks consisting of groups of small, inexpensive nodes, which collect and disseminate critical data. Thus, sensor nodes have various energy and computational constraints, because of their inexpensive nature and ad hoc m...

New optical network technologies provide opportunities for fast, controllable bandwidth management. These technologies can now explicitly provide resources to data paths, creating demand driven bandwidth reservation across networks where an applications bandwidth needs can be meet almost exactly. Dynamic synchronous Transfer Mode (DTM) is a gigabit network technology that provides channels with...

Data aggregation in wireless sensor networks eliminates redundancy to improve bandwidth utilization and energy-efficiency of sensor nodes. This paper presents a secure energy-efficient data aggregation protocol called ESPDA (Energy-Efficient Secure Pattern based Data Aggregation). Unlike conventional data aggregation techniques, ESPDA prevents the redundant data transmission from sensor nodes t...
