Coding-aware routing can create more coding opportunities by selecting the proper routing path. The main challenge in exploiting network coding is how to develop an effective network coding conditions. In this paper, we develop the active intersession network coding (AINC) which can create more intersession network coding opportunities than the general intersession network coding (GINC) by actively exploiting the redundancy information in the network with the deliberately built bridge links. With the aim to find multiple candidate parallel paths for each unicast, the conventional Bellman-Ford algorithm is enhanced. Built on AINC and the enhanced Bellman-Ford algorithm, we propose the active intersession network coding-aware routing (AINC-AR) scheme for the wireless network which supports multiple unicasts. The basic idea of AINC-AR is to select the path from all available candidate ones by jointly considering the effects of network coding gains and path costs on the overall network costs, so as to minimize the total network costs. Simulations are conducted to demonstrate the advantages of AINC-AR over GINC-AR and the conventional routing scheme without considering network coding.
