Wireless sensor and actor networks (WSANs) are formed by the collaboration of sensor and actor nodes. Whenever there is occurance of an event of iritrest, i.e., object detection, earth quake, water level detection, sensor nodes sense it and send information to the actors. Actors are responsible to take prompt decisions and react accordingly. In some situations, it is required to send event data to a group of nodes simultaneously in a certain time period. Multicast routing is an efficient way to disseminate event information to multiple destinations. Therefore, an efficient and reliable multicast routing is required for wireless sensor actor networks. In this paper, we propose a QoS based rnulticast routing (QMR) protocol and coordination framework for WSANs. QMR provides multicast routing using actor directed clustering protocol, which configures the sensor nodes in the form of clusters and propagates the event information to multiple cluster heads as well as actors. The multicast problem is formulated as a Linear Integer Program whose objective is to minimize the number of active sensor nodes in setting multicast routes such that data are received by all the members of multicast group. Simulation results show that, by using ADCMP, cluster heads efficiently deliver data to actors with minimum delay that helps for taking a quick action and thus serving its purpose of sensing and reacting in the deployment field.
