[ns] How to aggregate data in Cluster Head

[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 bytes). After that, CH will
aggregate data from 2n bytes into 2 bytes.

Rgds,

Tuan
