---------------------------------------------------------------ABSTRACT-------------------------------------------------------Wireless Sensor Networks consist of small nodes with sensing and computation, communication capabilities. Wireless network are highly dependent on specific application and are constrained by energy, storage capacity and power. To increase the lifetime of networks, energy...

One important performance index of routing mechanisms in sensor networks is sensor lifespan. In our settings, sensors are energy-constrained by batteries and located far away from the access point. A sensor dies once its battery dies. Since the radio transmission consumes a lot of energy, researchers proposed several routing mechanisms to save energy to prolong the sensor lifespan. So far, the ...

Server-centric data center architecture has been proposed to provide high throughput, scalable construction and error tolerance with commodity servers and switches for cloud data centers. To fully utilize those advantages of servercentric data center, an effective routing algorithm to find high quality multiple paths in Server-centric network is needed. However, current routing algorithms canno...

Recently, Opportunistic Networks (OppNets) are considered to be one of the most attractive developments Mobile Ad Hoc that have arisen thanks development intelligent devices. OppNets characterized by a rough and dynamic topology as well unpredictable contacts contact times. Data is forwarded stored in intermediate nodes until next opportunity occurs. Therefore, achieving high delivery ratio cha...

Two-echelon distribution systems are often considered in city logistics to maintain economies of scale and satisfy the emission zone requirements cities. In this work, we formulate two-echelon vehicle routing problem with stochastic demands as a chance-constrained optimization problem, where total demand customers each second-echelon route should fit within capacity high probability. We propose...

We present a novel Reliable, Real-time Routing protocol (3R) based on multipath routing for highly time-constrained Wireless Sensor and Actuator Networks (WSANs). The protocol consists of a newly designed routing metric and a routing algorithm utilizing this metric. Our routing metric enables strong Quality-of-Service (QoS) support based on parallel transmissions which significantly reduces tra...
