[ns] How to aggregate data in Cluster Head

2008-11-12 Thread Tuan Nguyen
Dear all, I don't know how to simulate LEACH protocol in WSNs with aggregating data at Cluster Head. Detail: The network is divided into many clusters. Every cluster has a Cluster Head and node members. In every cycle, all node members (n nodes) send data to CH (suppose packet's length is 2

Hi Douglas To put the nodes in sleep mode, you can use a timer and your nodes will be in the sleep mode or in active mode as the timer expires and you can do this in Node.cc file. Hope it helps. Regards Mubashir Husain Rehmani Lip6, UPMC, Paris, France. 2008/11/12 Douglas Restrepo [EMAIL

I think the LEACH itself doesn't consider data aggregation at cluster head. You can find more with the LEACH source code (please ask the authors for it) Cheers, Nguyen Lan. Tuan Nguyen wrote: Dear all, I don't know how to simulate LEACH protocol in WSNs with aggregating data at Cluster
