  • In this paper we propose an adaptive congestion control algorithm using cross layer design, which out-performs even during constrained situation. For analyzing the performance we have chosen four popular routing protocols such as AODV, DSR, DSDV and TORA. We also observe through simulation in NS2 that AODV out-performs other routing protocols in normal situation and DSR out-performs in constraint environment.

  • In this paper, we propose a bitrate adaptation algorithm at the client side in real time combined with a SDN-based dynamic path selection for HTTP-based video streaming. Experimental results show that the proposed method can provide users with better Quality of Experience (QoE) with lower number of rerouting times, higher average quality and smoother video quality than existing non-SDN methods under different scenarios of bandwidth fluctuations.

  • Research in the field of vehicle routing is often focused on finding new ideas and concepts in the development of fast and efficient algorithms for an improved solution process. Early studies introduce static tailor-made strategies, but trends show that algorithms with generic adaptive policies - which emerged in the past years - are more efficient to solve complex vehicle routing problems.

  • This paper presents the parameter adaptation values for ACS experimental set-up in validating its performance. Possible values of each parameter within a defined range were employed. Experiments were conducted to obtain the best value of each parameter to be used for throughput, energy consumption, and latency. Results of this study can be adopted to achieve optimal performance for the packet routing process.

  • To overcome the challenge, this paper presents an investigation on jointly optimal joint routing, scheduling, channel assignment and power control in multi-radio multi-channel wireless mesh networks using a MAC layer based on Time Division Multiple Access (TDMA). In which, a discrete fashion of power control and physical interference model is considered to find out an optimal solution for given rate demands. The computation complexity is reduced by applying the column generation algorithm in the optimize problem.

  • In this paper, we introduce an inventory routing problem with network disruptions. In this problem, not only decisions on inventory levels and vehicle routing are made simultaneously, but also, we consider disruptions over the networks in which a number of arcs are vulnerable to these disruptions, leading to an increase in travel times.

  • This study proposes a hybrid heuristic method based on the Greedy Randomized Adaptive Search Procedure (GRASP) metaheuristic and the Clarke and Wright Savings algorithm, to solve a VRPLC with several loading and routing constraints that have not been considered simultaneously before. Experimental results show that the proposed procedure produces competitive solutions in short processing times. Lastly, the impact of the added operational constraints is also analyzed.

  • The other routing protocols have been proposed in WSN to improve QoS other restrictions such as the delay. The problem here is that the complexity of the routing protocol significantly increased with integration of more than one QoS parameter. Indeed, define a QoS route meets two or more countries not limited correlation (eg, delay, and bandwidth) is an NP- complete problem (Mellouk et al, 2007), because many limitations optimal path problem can not be solved in polynomial time.

  • This chapter describes the joint application of two soft computing methods – evolutionary algorithms and fuzzy reasoning – to the problem of adaptive distributed routing control in packet-switched communication networks. In this problem, a collection of geographically distributed routing nodes are required to adaptively route data packets so as to minimise mean network packet delay. Nodes reach routing decisions locally using state measurements which are delayed and necessarily only available at discrete sampling intervals. ...

  • The olive is one of the most ancient cultivated fruit trees. Olive cultivation has a very long history which started from the Third Millennium BC (Loukas & Krimbas, 1983) in the Eastern region of the Mediterranean sea and spread later around the basin following land and maritime routes to Italy, Spain, North Africa and France. Nowadays there are about 805 million of olive trees, 98% of which are grown in the Mediterranean countries (Tsitsipis et al., 2009). The foremost consuming countries are also the main olive oil producers.
