Energy efficiency might be the primary design goal for
MAC protocols in sensor-nets but it should not be the
only design goal. Optimization criteria such as latency,
reliable data delivery, and compliance with real-time
constraints may gain importance in the future.
整句话翻译，谢谢各位。
參考答案:能效可能是在传感器网络中针对MAC协议的主要设计目标，但它不应该是唯一的设计目标。如等待时间、可靠数据传送和实时控制这些优化标准在未来可能会得到重视。
