This paper aims to depict the performance of cluster based routing protocol (Leach protocol) and multipath routing protocol (Multipath Ring Routing protocol) for Wireless Body Sensor Networks where the mobility is a crucial constraint to handle. | International Journal of Computer Networks and Communications Security VOL. 2, NO. 11, NOVEMBER 2014, 392–399 Available online at: www.ijcncs.org ISSN 2308-9830 Performance Analysis of Multi-hop and Cluster Based Routing Protocols for Mobile Heath Monitoring MARYAM EL AZHARI1, AHMED TOUMANARI2 and RACHID LATIF3 1, 2, 3 ESSI, National School of Applied Sciences, Ibnou Zohr University, Agadir Morocco E-mail: 1maryam.ensa@gmail.com, 2atoumanari@yahoo.fr, 3latif_rachid@yahoo.fr ABSTRACT This paper aims to depict the performance of cluster based routing protocol (Leach protocol) and multipath routing protocol (Multipath Ring Routing protocol) for Wireless Body Sensor Networks where the mobility is a crucial constraint to handle. Previous works mainly dedicate the above mentioned protocols to Wireless Sensor Networks where the topology is static and support hundreds of sensors, however, their performance is expected to highly degrade when it comes to a mobile environment including a limited number of sensors. The results proved that multipath routing performs better than cluster based routing in both static and mobile topology.

Several protocols have been proposed to handle data packets routing in Wireless Sensor Netwoks [1], however these protocols cannot be applied directly to Wireless Body Sensor Networks since additional constraints are added such as : Energy supply, medical sensors tends to have a small size compared to normal sensors dispersed in fields, which implicates smaller battery size, thus a certain amount of .
