In this paper, two novel techniques are proposed to solve the problem of minimizing battery cost and delay for packets transmitted within a soldier worn body area network (BAN) and along a body-to-relay network (BRN) under the constraint of a stringent end-to-end packet error rate (PER) objective. The first technique combines slot reuse and transmission parameter optimization to minimize delay and battery cost in a BAN that is subject to delay-inducing interference from co- located BANs. The second technique applies analog network coding (ANC), cooperative communication (CC), and transmission parameter optimization along the BRN link to overcome the error-inducing ANC noise inherent of ANC-CC schemes and to further reduce battery cost and delay. Numerical results demonstrate that the two proposed techniques reduce battery cost and delay more effectively than other techniques in the literature. These results are beneficial towards applications such as monitoring the health of injured soldiers in military field hospitals.
