Lot streaming based job-shop scheduling problem using hybrid genetic algorithm
Job shop scheduling problems (JSSP’s) are computationally complex problems. Lot streaming (LS) is the process of splitting a job into sublots to reduce its makespan on a sequence of machines. A lot can be split into a number of smaller lots in JSSP. However, planning decisions become more complex when lot streaming is allowed. Thus, the solution can be minimized both the idle time and total working...

SQR-AODV: A stable QoS-aware reliable on-demand distance vector routing protocol for mobile ad hoc networks
In a mobile ad hoc network (MANET), the topology of the network may change rapidly and unexpectedly due to mobility of nodes. Thus, setting up routes that meet high reliability is a very challenging issue. Another important problem in the MANETs is the energy consumption of nodes. When the energy of a node is depleted, it stops working thus links break. Hence it is very important to find a route that has...
