In the case of wireless networks the scheduling decisions are made using counters called shadow queues. The results are also extended to the case of networks that employ simple forms of network coding. In that case, our algorithm provides a low-complexity solution to optimally exploit the routing–coding tradeoff. | International Journal of Computer Networks and Communications Security C VOL. 2, NO. 4, APRIL 2014, 137–141 Available online at: ISSN 2308-9830 N C S Probabilistic Splitting Table helps in back pressure based packet by packet adoptive routing in communication network Mrs. JAYASHREE S. YADANNAVAR Department of Information Technology, MIT AOE, Alandi (D),Pune E-mail: 1jaya_y25@ ABSTRACT In the literature we have studied each packet is routed along a possibly different path by using Back Pressure based adaptive routing algorithm. So there is poor delay performance and involve high implementation complexity. After studied Back Pressure algorithm with clearly, we have developed a new adaptive routing algorithm. Here we have designed probabilistic routing table that is used to route packets to per destination queue to decouple the routing and scheduling components of the algorithm. In the case of wireless networks the scheduling decisions are made using counters called shadow queues. The results are also extended to the case of networks that employ simple forms of network coding. In that case, our algorithm provides a low-complexity solution to optimally exploit the routing–coding tradeoff.

Each node maintains queues. Generally, each pair of nodes can communicate along a path connecting them. Thus, the number of queues maintained at each node can be as high as one less than the number of nodes in the network, ., | | = | | -1: In proposed system, the main purpose of this paper is to study the case of scheduling and routing the shadow queue extends, which brings new invention that the number of hops is minimized. In the antagonism the .
