Problem of simulation DV-HOP algorithm

[halima ghribi]

Hello everyone

 I have been trying to implement the DV-hop algorithm in the MICAz platform with 3 anchors and 12 nodes under Contiki cooja 2.6.In the first time the simulation workes fine and i get the result. but when i changed the values of the nodes and run the simulation again  it didn’t get me the result.I switch the same code in an other laptop with an other value of anchor an node. In the first time it work and get the result but in the second time it doesn’t work.the problem is i can not do many simulation with different value of anchor and node in my laptop. I get just one result  of simulation in my laptop and the code is correct.So can any one of you help me. 

thanhs.
