In this paper, at first, we show the analyses of transmission delay, energy consumption and data accuracy of non-aggregation, full aggregation and partial data aggregation with Markovian chain. The analytical results show that non-aggregation consumes much energy and full aggregation causes long transmission delay; but the proposed partial aggregation can trade off total delay, energy consumption, and data accuracy between non-aggregation and full aggregation. Then we intensively discuss the tradeoffs among energy consumption, transmission delay and data accuracy with a Trade Off Index (TOI). We discuss the TOI under the different conditions of accuracy dominant, energy dominant, and delay dominant. By comparing the TOI value among non-aggregation, full aggregation and partial aggregation in different data generation rates, we obtain the best TOI. The results show that with small data generation rate, non-aggregation is the best TOI; with moderate data generation rate, the partial aggregation is the best TOI while the data generation rate is large, the full aggregation is the best TOI. At last a multi view multi robot sensor network is discussed and a User Dependent Multi-view Video Transmission (UDMVT) scheme is introduced.
