Somalis are cattle-owners, not camel riders. Camels are very new to the culture, slightly under or over a thousand years I'd say. Somalis are much closer to their Nilotic neighbors in culture and custom, than North Africans or people of the near-east.
Many Nilotes in Kenya have significant Cushitic influence, particularly the Samburu and Maasai (they use the Gada system and whatnot), those are classified as Nilo-Hamites. However, you won't find any similarities between the pure Nilotes of South Sudan/North Uganda and Cushites. Those people are quite alien to Cushites.
