针对DSR和MEDSR协议负载平衡能力的不足，提出一种具有离散约束的最小能量DSR路由协议——DMEDSR。
According to the insufficiency of DSR and MEDSR route protocol, a constrained dispersion based minimum energy DSR routing protocol-DMEDSR is proposed.
因此，整型问题的约束放松并不一定会改进解决方案，因为可行域是离散的，而不是连续的。
Thus, a relaxation of the constraint of an integer problem does not necessarily improve the solution, because the feasible region is discrete and not continuous.
