  A Mobile Ad hoc network (MANET) is a self configurable network connected by
wireless links. This type of network is only suitable for temporary
communication links as it is infrastructure-less and there is no centralised
control. Providing QoS aware routing is a challenging task in this type of
network due to dynamic topology and limited resources. The main purpose of QoS
aware routing is to find a feasible path from source to destination which will
satisfy two or more end to end QoS constrains. Therefore, the task of designing
an efficient routing algorithm which will satisfy all the quality of service
requirements and be robust and adaptive is considered as a highly challenging
problem. In this work we have designed a new efficient and energy aware
multipath routing algorithm based on ACO framework, inspired by the behaviours
of biological ants. Basically by considering QoS constraints and artificial
ants we have designed an intelligent version of classical Temporally Ordered
Routing Algorithm (TORA) which will increase network lifetime and decrease
packet loss and average end to end delay that makes this algorithm suitable for
real time and multimedia applications.
