A wireless sensor network consisting of heterogeneous sensors is capable of dealing with more than one type of information about any region at a time. Sensor applications that cater to disaster relief require faster data delivery and effective connectivity than the other monitoring applications. Moreover, usually, sensors collect a single type of data. The authors' approach focuses on generating a tree based communication architecture that is made up of three different types of sensors and ensures that at least one sensor of each type is connected to the communication backbone; thereby forming a multi-tree.
