We approach the problem of computation in sensor networks from a parallel and distributed system's perspective. We define COSMOS, the Cluster-based, heterOgeneouSMOdel for Sensor networks. The model abstracts the key features of the class of cluster-based sensor applications. It assumes a hierarchical network architecture comprising of a large number of low cost sensors with limited computation capability, and fewer number of powerful clusterheads, uniformly distributed in a two dimensional terrain. The sensors are organized into single hop clusters, each managed by a distinct clusterhead. The clusterheads are organized in a mesh-like topology. All sensors in a cluster are time synchronized, whereas the clusterheads communicate asynchronously. The sensors are assumed to have multiple power states and a wakeup mechanism to facilitate power management. To illustrate algorithm design using our model, we discuss implementation of algorithms for sorting and summing in sensor networks. <\/jats:p>","DOI":"10.1142\/s012905410400256x","type":"journal-article","created":{"date-parts":[[2004,6,21]],"date-time":"2004-06-21T08:14:10Z","timestamp":1087805650000},"page":"485-506","source":"Crossref","is-referenced-by-count":16,"title":["A HIERARCHICAL MODEL FOR DISTRIBUTED COLLABORATIVE COMPUTATION IN WIRELESS SENSOR NETWORKS"],"prefix":"10.1142","volume":"15","author":[{"given":"Mitali","family":"Singh","sequence":"first","affiliation":[{"name":"Computer Science Department,  University of Southern California, Los Angeles,  California 90089, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viktor K.","family":"Prasanna","sequence":"additional","affiliation":[{"name":"Computer Science Department,  University of Southern California, Los Angeles,  California 90089, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf6","first-page":"30","author":"Chen J.
